Gene Expression - Essay Example Before we start to Compare and contrast transgenic methods for manipulating gene expression between Drosophila and vertebrate animals let us discuss in brief about what is gene expression and function of genes Gene expression Genes exert their effects on the phenotype. The biological information is contained in the base sequence of DNA. Gene expression is the process by which this information is made available to the cell. This has been described by the central dogma. This states that information is transferred from DNA to RNA and RNA to a protein. During expression gene synthesis from mRNA molecule, into which information has been transferred in the form of genetic code. This synthesis of mRNA from of the strands of the DNA molecule is called transcription. The first step in gene expression is called transcription. Two strands of DNA separate, only one them act as template for the transcription into mRNA in 5’ïÆ'  3’ direction. This strand is non coding (antisense) strand and the other stand of DNA is coding strand (sense strand). This synthesis of polypeptide chain or a protein from mRNA is called translation.... Many genes express whenever the product is required and the expression is regulated. These genes are called regulated genes. Certain genes are expressed as a function of the interaction between RNA polymerase with promoter without any regulation. Such genes are called constitutive genes. They are constantly needed for cellular activities. Flow of genetic information from DNA to protein through RNA was described by crick as central dogma of molecular biology. The studies of bacterial genetics indicate that all genes not only specify the structure of an enzyme but some of them also regulate the expression of other genes. These genes are called regulator genes. This concept of gene regulation has been studied by Franois Jacob and Jacques monod in 1961.the relationship between the nucleotide sequence of mRNA and amino acid sequence that constitute a polypeptide chain is called as genetic code. Gene expression in Drosophila melanogaster Introduction Heterochromatin was originally defined visually as the heavily staining region seen in both the meiotic and interphase nucleus (hietz 1928). The contrast between the openness of euchromantin and the compactness of the heterochromatic implied that the euchromatic is the location of most gene function and led to the neglect of heterochromatin. However, it has become increasingly clear that the nuclear genome is more than a collection of autonomous DNA sequence and that a deeper knowledge of the structure of the nucleus and the chromatin, including the heterochromatin, will contribute to our understanding of the gene expression. In Drosophila melanogaster heterochromatin accounts for approximately 30 % of the genome. Its properties have been studied since the advent

M3A1 - Essay Example Emotional intelligence, therefore, offers a way in which managers working in different cultural settings than their own can adapt and achieve success in their new setting. For example, Deirdre who works as a broadcast director for a London-based company was tasked to ensure all units adopt a single negotiating strategy. Instead of fighting it out with the managers who resisted this change, she had one-on-one meetings to find out their reasons for resisting. Later, she shared ideas with them and revised her negotiating methods to incorporate the approaches the managers had found successful. The managers chose to co-operate other than resist. An effective leader exhibits five components of emotional intelligence. These are self-awareness, self-regulation, empathy, social skills and motivation (Hofstede, 1985). He further explains that emotional intelligence is necessary for building trust, solving problems with others, participating productively in a group and creating a sense of identity and efficacy. Emotional intelligence, however, has its weaknesses as shown by Earley & Mosakowski (2004). They give an example of an American expatriate engineer working with two German counterparts. After some time of the Germans shooting down other people’s ideas, the American mistakenly equated the action of the two as that of all Germans. With emotional intelligence alone, the manager is unable to show how much of the behavior of the engineers had been idiosyncratic and how much was culturally determined. He did not know how to influence their actions (Earley & Mosakowski, 2004). Earley and Mosakowski state that human actions, speech and gestures that a person encounters in a foreign setting are subject to wide interpretations that may make misunderstandings likely and cooperation impossible (Earley&Mosakowski, 2004). Hofstede states

Jazz - Essay Example The slaves bought with themselves their music traditions (Cooke, 7-9).  There were grand dinners and festivals arranged which featured the African dances in the city of New Orleans. Similar gatherings occurred in  New England  and  New York. The African music lacked the harmony present in the European music but the rhythms reflected the similarity of the two music genres (Cooke, 11-14). An increasing number of black musicians eventually learnt how to play various European instruments in the early 19th century, especially the  violin. The black slaves who had come as a result of the slave trade had by now learned the harmonic style of  European music  and incorporated it into their own music styles (Cooke, 14-28). Many historians agree to it that jazz began just prior to the 20th century and its birthplace is the city of New Orleans. Prior to the World War I, the Creole band which was a band of New Orlean black musicians toured many parts of the country and therefore, jazz music was introduced to many cities like this. The Dixieland band group created the very first example of Ned Orleans style jazz by recording the music. The very first Blues number was the â€Å"Dallas Blues† recorded in the year 1912. There were many hit songs from different musicians in the 1900’s including Saint Louis Blues by W.C Handy and Indiana by Ballard MacDonald. The latter was the first recording by the Dixieland jazz band. Until the 1950’s, jazz was considered as music intended mostly for dancing (Tyle). Jazz is more than hundred years old but the actual circumstances of the birth of this music are rarely known because the recordings of the first jazz band were lost and therefore it is difficult to assume as to how it sounded, but it is possible to create an account of its emergence by gathering scraps of tit bits and information pieces. Jazz music was different. In the beginning, many musicians had worried about the impact of Jazz on the young generation, as such

Do an analysis synthesis of the chosen texts, cross pollinate issues Essay

Do an analysis synthesis of the chosen texts, cross pollinate issues raised in various texts - Essay Example In Gogol's The Overcoat, one can see the personification of this 'common man', in Akaky Akakiyevich who lived almost an invisible life in the society until he felt a wish to have a distinct identity by acquiring a new overcoat, a wish that costs him his life (Gogol). In the beginning of the story itself, he is depicted as some one â€Å"who cannot bite back† (Gogol, 29). Gogol has spend a lot of his narrative time explaining the name, Akaky Akakiyevich, even referring to his family name, Bashmachkin, which is supposed to have originated from the word, bashmak, which meant, shoe (29). Here, accidently, but rather meaningfully, we see a reference to shoe both in Heaney's poem as well as in Gogol's story. And the word shoe, is synonymous with the concept, downtrodden, in both these contexts. Throughout Gogol's story, Akaky Akakiyevich is treated as a shoe, which is a symbol of getting insulted, getting trampled under the feet. A shoe is thrown away when it is of no more use. In t he same way, the protagonist in this story is replaced by some other person in his office without worries from any side, as soon as the story of his death reaches there (Gogol, 55). Akaky Akakiyevich had been a man who was deeply immersed in his mechanical ways of work and life as if he himself was a well-oiled machine until he saw that his overcoat was worn out and it was making him cold while moving outdoors (Gogol, 35). It was using the savings from depriving himself of the meager comforts that he could afford added with an act of benevolence from his director that Akaky Akakiyevich could find the money to buy a new overcoat. Once he bought the coat and started using it, he was elated from his position as a commoner though for a brief while (Gogol, 44). A party was held to celebrate his new overcoat but after the party, as he was returning home, his coat was stolen, his efforts to get a legal remedy was stiffled by official apathy, he was insulted and fell ill and soon he dies (G ogol). In the narrative, Akaky Akakiyevich passes away just like the shoe that is dipped into the water and grows cold with an â€Å" unpredictable fantail of sparks Or hiss† (Gogol, Heaney 4). And Gogol has said in the story that, â€Å"at last he began to curse, uttering the most horrible words, so that his aged landlady crossed herself, never in her life having heard anything of the kind from him† (54). This image is so similar to the sparks or hiss that came out from the shoe just before the heat died out (Heaney). And it is a wasted protest. The progress of the story on these lines, show that when a down trodden person tries to improve his social status, it is treated as a crime and the punishment is death. When Heaney, in another poem of his titled At a Potato Digging, says that, â€Å" going down and down/ for the good turf, digging,† the same concept is implied- a search for dignity and depth that ends up in darkness and unending toils (23-24). An effort to rise above one's social backwardness appears to be an individual's personal problem on surface, but once he/she actually makes an effort to do that, suddenly it becomes evident that there are forces in action which would not let it happen. And

Education Psychology Research Paper Example | Topics and Well Written Essays - 750 words

Education Psychology - Research Paper Example The child also develops intellectually and is able to manage time, set goals and priorities, understand different meanings of words and develop morally. The child develops social skills including attempting to solve problems on their own. The child also tries to form social relationships and make lasting friendships (Morin, 2012). Jean Piaget explained the stages of a child’s cognitive development, which include the sensor motor stage occurring between birth and two years of age, preoperational stage from two to seven years, concrete operational stage starting from seven to eleven years, and formal operational stage occurring from adolescence to adulthood. Fourth grade students are in Piaget’s concrete operational stage of cognitive development. At this stage, students learn how to use logic appropriately. They demonstrate intelligence by manipulating symbols systematically and logically. They are also able to make sensible decisions and think hypothetically about observable objects. Children at this stage can also sort objects according to shape, size or color. They can also recognize the relationships between things in a sequential order. Moreover, they are able to classify objects depending on characteristics such as size or appearance. The child also understands that some objects can be chang ed to different states and reversed again, for instance, the deflation and inflation of a ball (Shaffer and Kipp, 2009). The child also goes through social development. Erik Erikson explained eight stages of psychosocial development, from birth to adulthood. Fourth grade students are at the industry versus inferiority stage. It occurs between the ages of approximately five to eleven years. At this stage, children develop pride in their abilities through social interactions. It is an important stage for developing self-confidence. At this stage, children are given opportunities to gain the recognition of their parents or teachers. For instance, they can be asked to draw, solve problems or write sentences. If they do them correctly, they are commended for their achievements. If teachers and parents commend and encourage children at this age, they will believe in their skills and have a feeling of competence. However, those children who are not encouraged by parents or teachers, but ar e punished and ridiculed instead will begin to doubt their abilities and develop low self-esteem (Underwood and Rosen, 2011). Lev Vigotsky’s socio-cultural theory explains that learning is a social process and human beings get their intelligence from the society. A child’s social interactions play an essential role in cognitive development. Vigotsky’s theory suggests that students should learn in an environment that is socially interactive. The learning environment should be supported with discussions, computers, problem solving, and collaborative writing, among others (Shaffer, 2008). By having knowledge on the social, intellectual and physical development of students, I will be able to teach more effectively in future. Teaching students at the concrete operational stage will involve the use of concrete visual aids to explain complicated ideas to them. I will also use familiar examples to explain complicated concepts and give the students a chance to manipulate objects. I will give students assignments that will require them to think analytically and logically. I will ask them to practice classifying ideas and objects. I will apply Erikson’

A legislative issue happen with coco cola in US. There Coco

Recommendations for Reducing Inconsiderate Partying in the UDR Apartme Research Paper - 1

Recommendations for Reducing Inconsiderate Partying in the UDR Apartment through a A No-Inconsiderate-Partying Contract - Research Paper Example A No-Inconsiderate-Partying (NIP) contract is recommended because it can effectively and efficiently prevent and resolve insensitive parties in the UDR apartment. The contract will have a section on empathy, designation of quiet hours, a recommendation of other outlets where renters can party, and sanctions for violators, including cancellation of the lease. I also suggest a party room for every floor and enhancement of the soundproof quality of all rooms. These are more costly suggestions but they can increase profits and improve the living experience and brand equity. Hence, the most cost-efficient and effective is the No-Inconsiderate-Partying (NIP) contract that has high management and renter acceptability and sustainability. I am a recurring victim of inconsiderate partying in the UDR apartment at Domain College Park. Some of the renters here party up to 3 a.m. during weekdays. Though the apartment has students and employees renters alike, many renters are actually students since this apartment is in College Park, and this really makes it more inconceivable how they can be quite insensitive to the sleep and studying needs of other students like them. I could not always tell them to lower their noises because I am afraid of dealing with drunken adolescents and adults and because there have been times when I told them to lower their noise, which they did for a few minutes, and then they increased the noise again. I have gone to the apartment staff of the UDR apartment at Domain College Park to complain about these party noises. The staff stressed that they have a â€Å"no-party† policy and that they would remind the room’s  inhabitants about it.   These partying noises continue up to now.    Clearly, the no-party policy is not effective in deterring or resolving insensitive partiers.  Ã‚
