Studies on Photosynthesis Using the Hill Reaction Report Lab
Studies on Photosynthesis Using the Hill Reaction - Lab Report Example The primary ââ¬Ëlight reactionââ¬â¢ stage requires light and involves the excitation of electrons of the chlorophyll. These electrons then proceed along a series of electron carriers embedded in the thylakoid of the chloroplast resulting in synthesis of ATP in the stroma and the reduction of NADP. The dark reactions of photosynthesis do not directly require light involve the use of ATP and NADPH formed during the light reaction (figure 1) (Berg et al., 553). Hill reaction named after its discoverer Robert Hill (1937) involves the photoreduction of an electron acceptor by the hydrogen atoms of water, along with evolution of oxygen. In laboratory, Hill reaction is demonstrated when isolated and illuminated ââ¬Ëchloroplastsââ¬â¢ reduce an electron acceptor present with it, and release molecular oxygen: The electron acceptors used in laboratory conditions are not the natural electron acceptors or NADP but instead are artificial electron acceptors (Walker, 109). These artificial electron acceptors intercept the electrons before they reach PS1700. Further they are generally dyes that change color when reduced e.g. DCIP (2,6-dichlorophenolindophenol). Thus Hill reaction can be written as: Thus using the above equation, rate of Hill reaction in isolated protoplasts can be experimentally estimated. The change in absorbance of the dye at 600nm measured under varied conditions of experiment gives the rate of Hill reaction occurring under the preselected set of conditions. Several of the detergents are also known to be inhibitors of photosynthesis such as DCMU [3-(3, 4-dichlorophenyl)-1, 1-dimethylurea], DNP [dinitrophenol] and triton-X etc. Chloroplast was extracted from deveined, washed and blot dried fresh baby spinach leaves. The standard fractionation protocol for extraction of chloroplasts was followed. 50g spinach leaves were homogenized in a pre-chilled blender jar along with buffered isotonic salt solution and antioxidant solution. The homogenate was

REGULATION AND MANAGEMENT IN THE GLOBAL COMMUNITY Essay - 1
REGULATION AND MANAGEMENT IN THE GLOBAL COMMUNITY - Essay Example This implies that most people in the corporate cultures tend to thrive long within the industry by becoming emotionless. For instance, most corporates have manifested this personality when those individuals managing the corporates have failed to maintain the ethical standards. This has often benefited a few individuals who become rich while those at the bottom end up being thrown on the streets when the corporates begin a downward spiral. The corporate governance is in dire need of regulation if the rights of the citizenry, as well as the integrity of the state are to be maintained. This is particularly important due to the fact that psychopaths have a tendency to taint nearly all the circles that they come into when establishing a contact. This implies that psychopaths can taint the state too, which is charged with the responsibility of establishing the extent of ethical and legal limits of the corporate behavior. This contamination of the state may occur in myriad ways. For instance, the intense corporate lobbying, in addition to the financial donations that corporates tend to extend to the state among other spheres of social influence, they may sometimes influence those in charge of making and overseeing the implementation of the law. To fully understand the link that likens corporate governance to a psychopath, Ullman (2004) provides diagnostic criteria for the same. To begin with, he points out that just like a psychopath; corporates tend to fail to conform to the set social norms and regulations that pertain to the practicing lawful behavior. This is commonly indicated by their repeated acts that pose clear grounds of arrest. This is mainly manifested through the ability of corrupt corporations to find their ways into powerful and key areas of the state using ways that go beyond the social norms. Some of these ways include seeking loopholes in the law to establish their claims, stock shares manipulation
An Effective Teacher Essay Example for Free
An Effective Teacher Essay The qualities that define an effective teacher are very complex in my opinion. Everyone seems to have different ideas as to what the key indicators are. They range from; professionalism, communication, professional development, managing, guiding and strategies. There are even those of the opinion that it doesnââ¬â¢t matter what you do, children will always learn. However I have chosen professionalism as I believe that it is an essential attribute to being an effective teacher. Professionalism is defined by Merriam-Websterââ¬â¢s dictionary as ââ¬Å"Characterised by or conforming to the technical or ethical standard of oneââ¬â¢s profession. (Belcher). In order to gain and preserve the respect and trust of students, parents and colleagues alike and to provide students with the best education possible it is important to demonstrate professional conduct and practice. The guidelines for professionalism in the teaching profession are provided by Code of Ethics, National Professional Standards for Teachers and Duty of Care. These define the ââ¬Å"whatâ⬠. The key however is being or acting professional, this is the ââ¬Å"howâ⬠, the effectiveness of a teacher. This is the true measure of professionalism. Some of the primary demonstrable characteristics or attributes of a professional teacher are communication, morals and ethics and professional development. Communication is an essential aspect in education, the means to send and receive clear messages to and from students, teachers, parents and community members. It establishes positive and effective relationships and connections with the involved parties. Communication can be in many forms namely verbal, non-verbal or written and used by teachers to constantly impart new knowledge or important information. The ability for teachers to apply the characteristics of good and effective communication in all its forms, to a diverse audience with different backgrounds and interests and to minimise the barriers, for example noise, misunderstanding or misinterpretation of the messages are the makings of an effective teacher. In the article by Prozesky, he states that the most effectual way to overcome these barriers is to have two-way communication with regular feedback provided by the receivers. Professional ethics is not achieved by only purely applying the ethical codes of practice nor professional standards which embody the core principles but by also applying professional skills and personal skills (caring and nurturing) and ethical behaviour in the form of attitude, intention, words, acknowledgement, respect (inside and outside of the classroom), fairness and equity with regards to individual circumstances, colour, creed, age, social-economic status, to name a few. Brock (1998) says that when dealing with ethics and professional standards there are two questions to ask; what should one do and what one should not do, what is right and what is wrong and what is appropriate and what is inappropriate. These questions result in a number of ethical dilemmas that face the teacher such as truth versus loyalty, individual versus community and religion versus morals. Early Childhood Australia has published a guide to help teachers deal with every day ethical dilemmas. According to Marsh (2010) ethical decisions have been categorised into five different levels of decision making. Open decision making, limited decision making, decisions made by the teacher, security seeking (delegation) and avoidance. Several ethical relationships exist within the dynamics of a school environment; these include ethical relationship between the teacher and the education system for example, the education system restricts teachers on what they should teach. The teacher and the principal, an example being that the teacher and principal have different values and the principalââ¬â¢s values will over ride those of the teacher. The teacher and the students where the teacher develops emotional bonds with his or her students and there is a mutual respect between teacher and student. The third quality that defines an effective teacher is professional development. In order to be a good teacher you need to be a good learner too. The demands on teachers to find new ideas and forms of teaching are increasing. Teachers need to be innovative and therefore attend professional development days which will help them continuously enhance their competencies and provide their students with problem solving skills and advanced thinking thus elevating them to higher levels of achievement. The desire to expand their knowledge base, stay current and gain a broader exposure to information provides this opportunity. Through numerous examples it is clear how important communication, ethics and professional development are to professionalism. These attributes will help teachers to be more effective in imparting knowledge and wisdom to their students. All of these attributes will allow the students to really focus their energies on learning and engaging with their education. Even though all of the attributes are vital for effective teaching one must never forget that the purpose of effective teaching is ââ¬Å"that teachers make a difference, (Boyd, 2009).

Importance of Authenticity in Tourism
Importance of Authenticity in Tourism How important is authenticity in tourism? Introduction The purpose of this study record is to explore the theme of authenticity as expounded by different authors. The record will provide an overview of my reading during the course of the year, and will present an examination of the different approaches to the topic by the selected authors, and present these approaches in the wider context of writing on the importance of authenticity in tourism. Daniel Boorstin (1964, 1985) The Image: A Guide to Pseudo-Events in America. 2nd ed. New York: Athenaeum Boorstin writes about the demise of the traveller who seeks authentic experiences and the rise of mass tourism. For Boorstin, real travel belonged to a golden age that was now lost where whatever the traveller saw ââ¬Å"was apt to be what really went on thereâ⬠. Whereas contemporary travel was a pseudo-event made up of ââ¬Å"specimens collected and embalmed especially for him, or attractions specifically staged for himâ⬠(1961:102). Boorstin was adamant that the tourist no longer wanted authenticity, even going so far as to argue that a French singer singing in accented English was more appealing to the Anglophone tourist than the singer singing in her native language. Similarly, says Boorstin (1961: 106), the American visiting Japan is not looking for authentic Japanese culture but rather ââ¬Å"what is Japeneseyâ⬠. These contrived experiences had four characteristics, said Boorstin, they are not spontaneous or natural, they are designed to be reproduced, the relationship between the event and reality is ambiguous, and the contrived event becomes normal over time as it becomes perceived as being authentic. The theme in Boorstinââ¬â¢s book is that mass tourism is an impediment to experiencing other cultures and that the masses do not want to experience authentic culture anyway, preferring the contrived to the authentic. In reading Boorstin, his scepticism comes through very clearly but also you are left with a lingering sense of the authorââ¬â¢s arrogance. True authentic experiences could only be encountered in the golden age when none but the truly wealthy could afford to travel. For Boorstin, the opening of the leisure market to a wider range of social classes ruined the authenticity of the experience for the privileged and the educated and gave access to travel to people who couldnââ¬â¢t possibly understand the experience except at the most base and contrived level. Boorstinââ¬â¢s approach was taken forward by MacCannell who disputed that tourists wanted pseudo-events and it is McCannellââ¬â¢s work we shall consider next. Dean MacCannell (1989) A new theory of the leisure class. 2nd ed. University of California Press. This book was first published in 1976 and appears to be cited widely in books and articles on authenticity in tourism. MacCannell writes from the perspective that progressiveness has failed people and people use tourism to give their lives greater sense and meaning, and in seeking sense and meaning in other cultures people are highlighting that they feel isolated and alienated in their own culture. Touristsââ¬â¢ disillusionment with the nature of work in industrial society drives them to travel and to travel further, as they try to penetrate the ââ¬Ëbackââ¬â¢ of life where truth and authenticity can be found. This notion of life having a ââ¬Ëfrontââ¬â¢, ââ¬Ëbackââ¬â¢ and ââ¬Ëoutsideââ¬â¢came out of the work of Goffman (1959) who used the metaphor of the stage to examine the perceptions of the individual to the performance. The front stage is the official perspective, while the backstage is presented as being more honest as the individual has an awareness of the disputes and difficulties that are occurring. The outside represents segregation where the individual is unable to gain access to what is going on on stage. Authenticity in tourism, says MacCannell, comes from an awareness of what is going on behind the scenes where all is not sanitised for public consumption. MacCannell highlights the falseness of the distinction between mass tourist, researcher, travel writer and authentic traveller and puts forward the view that the mass tourist is as much in search of authenticity as the researcher or travel writer. MacCannell notes ââ¬Å"longstanding touristic attitude, a pronounced dislike, bordering on hatred, for other tourists, in a they are the tourists I am not equationâ⬠(1989: 602). MacCannellââ¬â¢s perspective particularly resonated with me as when travelling I have noticed people, including myself, wanting to distinguish themselves as separate from the masses, somehow being more distinguished or more credible as independent travellers rather than mass tourists. As well as noting the views of those who think that tourism will ultimately destroy itself[1], Iââ¬â¢m also starting to recognise the irony of my travelling to seek an authentic travel experience while at the same time willingly participating in the growth of tourism. Howe ver, while MacCannellââ¬â¢s perspective does resonate, I would suggest that MacCannellââ¬â¢s position is on one sense just as polarised as Boorstinââ¬â¢s. From Boorstin (1985), we get the perspective that all that tourists want is a superficial and contrived experience, whilst MacCannell proposes that all tourists are in pursuit of the real ââ¬Ëbackââ¬â¢ and authentic experience but are denied this by being presented with inauthenticity. In reality, it seems likely that the truth would be some where in between. Erik Cohen (1995) Contemporary Tourism-Trends and Challenges: Sustainable Authenticity or Contrived Post-Modernity?, in Change in Tourism: People, Places, Processes, edited by Richard Butler and Douglas Pearce. London: Routledge. Cohen has written extensively on authenticity in tourism across several decades and as well as challenging existing ideas, it is clear that he has enjoyed conducting fieldwork and written a substantial amount on tourism development in developing countries. Cohen notes that while tourism has hugely benefited the country in terms of economic development there are significant downsides including the growth of Thailandââ¬â¢s sex trade and related criminal activities. Cohen breaks Thailandââ¬â¢s tourism development down into four areas of change. The first is what he terms the massification of the industry which denotes the huge rise in the numbers of tourists entering the country. The second is the dispersion of tourism, from Bangkok and its environs across the country from Phuket in the south to Chiang Mai in northern Thailand. Tourism is continuing to spread in Thailand, with tourists venturing into the Golden Triangle in the north and into areas such as Krabi in the south. The t hird change identified by Cohen in that of heterogenisation, which is the process in which the nationalities of the tourists and the variety of attractions and amenities become more similar. Finally, says Cohen, there is regionalization at work. This can be seen by Thailandââ¬â¢s positioning of itself at the heart of an emerging regional tourism industry in Southeast Asia which includes Burma, Laos, Cambodia and Vietnam. As the tourism industry in Thailand develops, the Thai government is trying to encourage international tourism ââ¬â due to its greater revenue generating potential ââ¬â but is also trying to encourage domestic tourism. The reason for this is that domestic tourism minimizes foreign exchange leakage from the economy. The growth in tourism leads to continuing expansion into new areas and the further diversification of tourist activities, including the development of both natural and ââ¬Ëcontrivedââ¬â¢ activities. How these activities will balance out depends on dependent the Thai tourist economy depends on Europe, as Cohen notes that European tourists generally prefer contrived attractions such as shopping, theme parks and entertainment facilities. There will also be an increasing discrepancy between the tourist image of an idyllic location and the increasing pollution and urban development of Thailandââ¬â¢s beach towns. The increasing development of Thailand has led so me to argue that there should be a greater focus on authentic tourism and ecotourism is particularly promoted by some writers (Bottrill and Pearce, 1995; Honey, 1998). Cohen, however, argues that ecotourism principles are applicable to any type of tourism and that stringent or exclusive definitions of ecotourism are unnecessarily restrictive. From Cohenââ¬â¢s perspective, most tourists engage in mass tourist activities as well as alternative activities. The desire for authenticity can be measured by the touristââ¬â¢s willingness to forgo comforts such as comfort itself, familiarity and convenience in order to achieve what they perceive is a more authentic experience. Mass tourism and authentic tourism are not alternatives but a spectrum or continuum where the search for authenticity can be observed and measured. The importance of Cohenââ¬â¢s work is in how it has continued to challenge and develop our understanding of authenticity. As we saw earlier, McCannellââ¬â¢s (1976) scholarship focused on the concepts of alienation and authenticity but Cohen took this further. Cohen broadened McCannellââ¬â¢s conceptions and applied them to touristsââ¬â¢ perceptions of authenticity. Cohen has also developed the work of Boorstin[2]. As has been noted, Boorstin was very pessimistic about authenticity and his approach remained that of a sceptic. For Cohen, however, the idea of a universal authenticity was questioned and challenged. Cohen comes to the conclusion that authenticity means different things to different people and therefore what appears authentic to one tourist (or host) will not appear authentic to another. Building on this, we can see that the importance of authenticity can also be determined to be socially constructed, and its importance variable depending on the perceptions of the person considering the issue. This appears similar to the theoretical perspectives of the social constructivists where meaning is seen to emerge and is constantly changing. This view appears to have gained some following in tourism research with writers including Dearden and Mitchell (1997) and Sharpley and Sharpley (1997) sharing this perspective. Auliana Poon (1993) Tourism, Technology and Competitive Strategies. Oxford: CAB International. Poon writes about alternative tourism and puts forward the view that alternative tourism is more exclusive than mass tourism and is diametrically opposed to mass tourism in terms of consumers, production, technology and management. Poon argues that mass tourism comprises rigidly packaged and inflexible holidays when deviation from the package is rejected because of the cost implications that deviation would incur. There is also a mass replication of identical rooms or apartments to allow the operators to reap the benefits of economies of scale, and there is mass (undifferentiated) marketing again with hotel and holiday branding for reasons of economies of scale. Finally, according to Poon, mass tourism features mass consumption with little regard for the cultures of the tourist destinations. The alternative, according to Poon is a form of tourism that embraces flexibility and specialisation which provides a more personalised form of tourism. The alternative scenario also gives greater consideration to the tourist destination and actively considers culture and environment. The sustainability of alternative tourist destinations are therefore paramount under alternative tourism and attempts are made to pursue development in a culturally and environmentally sensitive and considered way. The motivation for tour companies to pursue alternative tourism can be seen in the potential it provides to differentiate itself in the marketplace. Mass tourism has saturated the market and to stand out to the consumer the travel companies must offer something different and authenticity is this difference. Having considered the work of Boorstin and MacCannell, and also Cohen, it becomes more difficult to accept a further attempt to present authenticity as a pure and exclusive form. It is easy to see that the concept of authenticity is useful in an academic sense, as a key component in a model, or a concept in which to frame a debate, but more difficult to see its existence in a pure form. In addition to considering authenticity as the polar opposite of mass tourism, there is another perspective: that mass tourism has merely reinvented itself into a more socially acceptable form. Fernandes (1994: 4) points out, ââ¬Å"the mainstream tourism industry has merely tried to invent a new legitimation for itself, the ââ¬Ësustainableââ¬â¢ use of the environment including the preservation of nature as an amenity for the already advantagedâ⬠. John Urry (1990) The Tourist Gaze.London: Sage Urry notes the rapid development of tourism and uses a metaphor of an omnivorous creature to highlight what he sees as tourists devouring the planet in their ââ¬Ëconsumingââ¬â¢ of destinations. Urry (1990:1) states that when we travel ââ¬Å"we gazeâ⬠and ââ¬Å"the gaze is socially constructedâ⬠. The gaze is not a single gaze regardless of nationality or social class, but emerges from who we are and goes on to shape us and well as that gazed upon. Urry charts the development of the tourist industry in the UK and looks at the rise of mass tourism in Victorian Britain the development of the British coastal resorts, the mass tourism provided by holiday camps, and the introduction of a new flexibility from the 1960s onwards as people travelled to European destinations. Mass marketing provided representative images which gave tourists an understanding of the destinations available and these are duplicated in the destinations themselves and in place promotion. Urry urges the development of the post-mass marketing tourist or what he calls that post-tourist who seeks to find authenticity and shirk the artificial and staged events offered by the tourism operators. This builds on Cohenââ¬â¢s work which argued that the local culture becomes a contrived commodity and, without peopleââ¬â¢s consent, operators take local culture and renders it meaningless. Urryââ¬â¢s work has come under criticism with some arguing that he has over-stated the decline of mass tourism. Indeed, package holidays to Orlando and Phuket appear to have a great deal in common in terms of fun and pleasure seeking as the mass tourism in Blackpool of earlier generations. Urryââ¬â¢s ââ¬Ëgazeââ¬â¢ has been criticised as being inadequate; Prentice (2001) puts forward the need to look at the subjective mental state felt by individuals while Ooi (2002) argues that the subjective nature of experience means that as well as being multi-faceted, ââ¬Å"experiences are embodies in peopleâ⬠and can ââ¬Å"only be expressed to and not felt by other peopleâ⬠. Ning Wang (2000) Tourism and Modernity: A Sociological Analysis. Tourism Social Science Series. Oxford: Pergamon. Having read perspectives from the objectivists Boorstin and MacCannell, and the social constructivist perspectives, it was interesting to see how Wang appeared to bring these perspectives together with a postmodernist perspective, based on the work of Baudrillard and others. Wang argues that authenticity should be broken down into authenticity of object and authenticity of experience. Authenticity of object refers to the authenticity of what is being observed, and this is further broken down into objective, constructive and post modern forms with the post modern form rejecting authenticity completely, while authenticity of experience refers to a personââ¬â¢s own personal experiences. Wang puts forward the view that authenticity is not inherent and identified characteristics that can be attributed to the constructivist conceptions of authenticity, namely that there is no fixed origin of authenticity, that what we consider original and authentic can be contested, notions of authenticity are pluralistic, and that authenticity is often declared when something conforms to tourist expectations. Wang also put forward the idea that inauthentic experiences can become authentic over time. This process, which Wang terms ââ¬Ëemergent authenticityââ¬â¢ was also put forward by Cohen and promotes the primacy of the tourist perception of the experience and, as Picard and Robinson remind us, ââ¬Å"all events were once createdâ⬠and that ranking authenticity is ââ¬Å"highly questionableâ⬠(2006: 134). Wangââ¬â¢s focus on a personââ¬â¢s own experiences is interesting as so much of the debate on the importance of authenticity has been about the authenticity of the objects being seen. Wang notes that tourists are ââ¬Å"in search of their authentic selves with the aid of activities or toured objectsâ⬠(2000:360). This search for our authentic selves can be liberating, a desire for experiences that are outside of our daily lives, but can also be restricted by itineraries and other constraints. The importance of authenticity in tourism is, for Wang, a feeling or perceiving of authenticity rather than its fixed existence in cultural objects. Conclusions From this study record we can see that many writers have highlighted the importance of authenticity but there is inconsistency about what authenticity entails. For Boorstin, mass tourism ruined any chance of experiencing authenticity and authenticity that not something that the masses sought even if it were attainable. MacCannell considered that authenticity could be equally sought by the mass tourist or researcher but held that the tourism industry was denying the people an authentic experience. Cohen offered a perspective on authenticity that incorporated both the tourist and the host but offered the possibility that one party might consider an experience authentic while the other did not; Poon considered authenticity and mass tourism to be diametrically opposed, while Urry built on Cohenââ¬â¢s work and presented the view that culture had become such a contrived commodity that it had been rendered meaningless. Finally, Wang presented what is almost a capstone perspective, bringi ng in the earlier objective and constructivist perspectives to present a broader representation of the importance of authenticity as an existential experience.

Immanuel Kants Foundations of the Metaphysics of Morals Essays
Immanuel Kant's Foundations of the Metaphysics of Morals In his publication, Foundations of the Metaphysics of Morals, Immanuel Kant supplies his readers with a thesis that claims morality can be derived from the principle of the categorical imperative. The strongest argument to support his thesis is the difference between actions in accordance with duty and actions in accordance from duty. To setup his thesis, Kant first draws a distinction between empirical and ââ¬Å"a prioriâ⬠concepts. Empirical concepts are ideas we reach from our experiences in the world. On the other hand and in contrast, ââ¬Å"a prioriâ⬠concepts are ideas we reach as an end point of reasoning prior to or apart from any experience of how things occur in the world. Kant then claims that moral actions are supposed done for the reason of morality alone. This train of thought leads to the conclusion that an understanding of morality must be based on ââ¬Å"a prioriâ⬠concepts of reason. Truly moral ideas are then universally valid if and only if they are based on ââ¬Å"a prioriâ⬠concepts. From this idea of ââ¬Å"a prioriâ⬠concepts, Kant begins his thesis with the notion that the only thing in the world that is a qualified good is the ââ¬Å"good willâ⬠, even if its efforts bring about a not necessarily good result. A ââ¬Å"good willâ⬠is good because of the willing that is involved. Two main implications arise with this idea of the ââ¬Å"good willâ⬠. The first implication is moral actions cannot have impure motivations. There are many impure motivations but Kant tends to focus mainly on the motives of the pursuit of happiness and self-preservation. Second, moral actions cannot be based on the speculations of the probable results. This action is not good in itself but good because it brought about a more desirable outcome. Thus, Kant arrives at the conclusion that for an action to be considered to have genuine moral worth its motive must be that of dutifulness to moral law. In Foundations of the Metaphysics of Morals, Kant lays out three propositions about duty. The first is the will is a morally good action if it is done in accordance from duty, as opposed to an action done in accordance with duty. The second proposition is that actions are judged by the "maxim" or principle that was the motivation behind the action. If someone undertakes an action with the only motivation being that of a sense of duty, they are followin... ...viously that you will be more probable to engage and look to engage in more actions that will give you this appeal and instant gratification. This is not an ideal situation because placing a slight neglect to a duty or obligation that you might not find appeal in defeats the purpose of completing all of the obligations set for us to go through with. à à à à à Kantââ¬â¢s thesis has strength in the fact that the universal law seems closely related to the golden rule, which is do on to others as you would have others do on to you. With a statement as such it is awfully arduous to not perform a moral action. The weakness still lies in the fact Kant takes little to no consideration to humansââ¬â¢ natural emotions and feelings. Leading a moral life does not have to be a melancholy life, one in which you are bound to an endless amount of duties that you can seek no joy in. Whether or not Kant intended to make morality seem like torture, it appears it comes off in this manner. Kantââ¬â¢s overall view of morality appears near flawless. If there was a manner in which he could have incorporated a leeway for some emotions, I feel his thesis is in actuality how each individual should lead his or her life.

Ligation of EGFP into pET41a(+) vector transformed into E. coli cells :: PCR amplification of extracted DNA plasmid
Ligation of EGFP into pET41a(+) vector transformed into E. coli cells followed by PCR amplification of extracted DNA plasmid for success evaluation along with gel electrophoresis at each step. Introduction Enhanced green fluorescent protein (EGFP) was originally isolated from a bioluminescent jellyfish called Aequorea victoria. As suggested by the name, this protein fluoresces green when exposed to light in the ultraviolet range. The ultimate goal of the following experiment was to successfully create a pET41a(+)/EGFP recombinant plasmid that was transformed into live E. coli cells. The success of this transformation could be evaluated based on whether EGFPââ¬â¢s fluorescence properties were displayed by the colony in question. The proteinââ¬â¢s fluorescence properties ââ¬Å"triggered the widespread and growing use of GFP as a reporter for gene expression and protein localization in a broad variety of organismsâ⬠(Ormo, et. al., 1996). Although EGFP and GFP differ for a few amino acids that make EGFPââ¬â¢s fluorescence mildly stronger, the basic principle that such a protein allows for the evaluation of transformation success remains intact. The first step of the experiment was ligation, and the objective was to insert EGFP cDNA into a restriction cut pET41a(+) vector to obtain a recombinant plasmid that would express green fluorescent gene. pET41a(+) was the choice of vector to ligate the EGFP into. Its structural design and genomic sequential properties render it especially well-suited for cloning and high-level expression of peptide sequences. This 5933 bp circular vector contains a built in sequence for Kanamayacin resistance gene. ââ¬Å"Rooting of non-transgenic shoots was completely inhibited in all culture media containing kanamycinâ⬠(Montserrat, et. al., 2001). This allowed the growth of recombinant and non-recombinant colonies of E. coli, all of which contained the vector insert. Once the recombinant plasmid was obtained, it was then inserted into E. coli cells through transformation. From a successful transformation, we expected the bacterial cells to translate the inserted EGFP sequence into its protein form. The bacteria cultures were plated on petri dishes containing growth supplement, Luria Broth (LB), an antibiotic: Kanamycin, and IPTG which induced the fluorescence property within successfully transformed bacterial colonies. Different variants of the petri dishes were also included as control and unknown. The miniprep consisted of isolating the DNA plasmid from the bacterial cells. This was used to identify the success of EGFP ligation into pET41a(+) vector upon restriction digest and gel electrophoresis. Additionally, Polymerase Chain Reaction (PCR) was run on the isolated DNA plasmids with one of the primers specifically annealing to a part of pET41a(+) sequence and the other annealing to the EGFP gene.

Gillian Clarke Essay
Before even reading ââ¬Å"Miracle on St Davidââ¬â¢s Dayâ⬠, I knew that something very special was going to happen from the word in the title ââ¬Å"Miracleâ⬠. Clarkeââ¬â¢s use of this word suggests that an amazing event is going to occur and that the poem is therefore going to be emotional and poignant. Gillian Clarke uses the first verse of the poem to create a pastoral idyll due to the use of personification-ââ¬Å"An afternoon yellow and open mouthed with daffodilsâ⬠. This conjures a happy and warm image of daffodils with their trumpets open wide, laughing in the sunlight, and it successfully personifies the flowers. Clarke also places people in the description to make it seem even more vivid in our minds-ââ¬Å"the rumps of gardeners between nursery shrubsâ⬠. The line, ââ¬Å"country house, guests strollingâ⬠pulls together a vivid image of a beautiful, opening scene in the readerââ¬â¢s mind. Clarke also introduces the importance of nature right at the beginning of the poem in this first verse. lAt the start of the second verse, Clarke dramatically dispels the pastoral idyllic that she created in the first verse. ââ¬Å"I am reading poetry to the insaneâ⬠is a blunt line, completely in contrast to the last verse as it is so insensitive. As readers, we instantly realise the harsh reality of the situation that she is in fact in a mental institution. Clarkeââ¬â¢s dispelling of the original image is effective because it catches the readerââ¬â¢s attention immediately as it is a completely unexpected twist. It also makes the poem poignant because it makes the readerââ¬â¢s realise that there is never a perfect place and that there is always suffering around. Clarke goes on in this verse to describe some of the patients around her and the length of their mental disorders-ââ¬Å"An old woman interrupting offers as many buckets of coal as I need. Clarke describes the poignant image of a schizophrenic, beautiful boy absorbed in her poetry making us realise that her poetry may be powerful for these people. After verse two, Clarke introduces verse three by stating ââ¬Å"on a good day, they tell me laterâ⬠to show how the split between a verse is a like the dramatic split personality of a schizophrenic. In verse three, Clarke goes into more detail about her moving surroundings to build up a vivid idea of the situation in the readerââ¬â¢s mind. She describes ow the sun causes shadows of window bars into the room and how a woman is sitting in these shadows as if she is in a cage. ââ¬Å"In a cage of first March sun a woman sitsâ⬠. Clarke repeats the word not, ââ¬Å"not listening, not seeing, not feelingâ⬠to result in the woman appearing to be trapped inside herself and entirely vacant. Finally in this verse, Clarke writes, ââ¬Å"a big, big mild, man is tenderly led to his chairâ⬠. The use of the adverb ââ¬Å"tenderlyâ⬠makes us understand just how much care and attention these people need. Clarke continues with the poemââ¬â¢s tone of compassion in verse four, by the slow reading caused by several instances of pauses in the line due to commas such as ââ¬Å"â⬠¦ hands on his knees, he rocksâ⬠¦ ââ¬Å". ââ¬Å"I read to the big, dumb, labouring man as he rocksâ⬠also brings about the sad sense that although this man seems self-sufficient and big on the exterior he is mild and insecure on the inside and in the mind. Finally Clarke uses an oxymoron, ââ¬Å"I read to their presences, absencesâ⬠to show how although they are physically in the room, some of their minds arenââ¬â¢t really there at all. In verse five, Clarkeââ¬â¢s writing makes everything suddenly change. The slow and thoughtful pace of the poem ends dramatically in a similar way that Clarke destroyed the pastoral idyllic after the first verse. Gillian Clarkeââ¬â¢s use of alliteration also strongly suggests that something special is about to happen, ââ¬Å"He is suddenly standing silently, huge and mild but I feel afraid. â⬠Clarke then cleverly uses two similes to portray the moment before the man speaks, ââ¬Å"Like slow movement of spring water or the first bird of the year in the breaking darknessâ⬠. These similes are closely linked to new life spring which is convenient because the poem is set on the first day of spring. We also grasp from Clarkeââ¬â¢s use of similes that the man is going to do something new. This is a significant and poignant moment in the poem because the man is so well-built and huge yet what he is about to do is something really big and special for everybody in the room and the reader, ââ¬Å"the labourerââ¬â¢s voice recites ââ¬ËThe Daffodilsââ¬â¢Ã¢â¬ The reaction to this manââ¬â¢s speech is shock and no one is able to speak. The nurses are speechless and prepared for violence from the man but even they freeze. The patients, some of which are seriously mentally ill also suddenly listen, ââ¬Å"the patients seem to listenâ⬠. It is effective and poignant, how Gillian Clarke then personifies the daffodils to match the characters and mood of the room. She expresses that even nature outside can react at this incredible moment. The hyperbole that she uses, ââ¬Å"a thousand, ten thousandâ⬠is an excerpt from the Wordsworth poem that the man is reciting. Clarke successfully employs this hyperbole to exaggerate the number of daffodils who stop to observe to the man breaking free of speech and his life. I think that the seventh stanza is the most heart-breaking stanza, especially ââ¬Å"Since the dumbness of misery fellâ⬠; because that implies that the man was once a happy child and only stopped talking and became miserable when something tore his life apart. This is poignant because it makes us imagine tragic events that could have stopped this man from speaking and that it really shows the power and impact that poetry can have. I think ââ¬Å"the daffodils are flameâ⬠is a very effective and clever way of Clarke to finish the poem because it is ending with the daffodils where it first started. The way that nature outside corresponds to the event in the room is truly miraculous. In verse six Clarke personifies the daffodils as ââ¬Å"still as waxâ⬠whilst the man is reciting and the daffodils are then ââ¬Å"flameâ⬠in the last verse during the manââ¬â¢s applaud (we can see a fiery theme). The poem is so poignant because of the way Clarke creates successful images and personification so that we can feel we are in the room at the time of the miracle. The pathetic fallacy at the end leaves readerââ¬â¢s reflective and astounded by the description in poetry of such an amazing account.
