Assignment-Synthesis of a Protein - Lab Report Example Errors in protein synthesis produce polypeptides displaying a gain of toxic function which may confer an alternate or pathological function on a normal, folded protein. In case of enzymes, the hydrophobic core provides structural stability for the molecule and amino acid changes may result in unstable protein product that is temperature sensitive. As the catalytic site of the enzyme is extremely sensitive, a single point mutation (either a deletion or insertion or substitution) may completely abolish function. 5. The above sequences represent those of eukaryotes as the intron or the non-coding region (codons from 24 to 66, including 66) had to be removed before translating it into a polypeptide or a protein. Whether sequence is eukaryotic or prokaryotic, it can be identified by the presence of introns and exons. In the case of prokaryotes, the initial RNA molecule or initial transcript is equivalent to the final mature RNA. In most eukaryotic genes, the initial transcript is processed so that the mature RNA is different. Most eukaryotes have genes that contain introns that do not code for polypeptides. However, prokaryotic genes do not contain introns. Eukaryotic RNAs, after transcription, have the intron sequences that are removed/ spliced in order to produce the final mature RNA. The sequences in eukaryotes that are represented in the final RNA and code for amino acids in a polypeptide are called exons. 6. The tRNA anticodon sequence that would build this protein is complementary to the mRNA sequence. The tRNA anticodon bonds to a given mRNA codon, by hydrogen bonding between A-U pairs and C-G pairs. The above sequence represents the intron or the non-protein-coding region of the initial mRNA transcript. The intron sequences are spliced in order to produce the final mature RNA in eukaryotes. Introns play important roles in gene regulation. One of the functions of introns is that they

Development of the Social Self Essay Example | Topics and Well Written Essays - 750 words

Development of the Social Self - Essay Example The ability to develop and maintain a consistent and functional sense of the self in the increasingly superficial and anonymous interpersonal context of modern mass societies is widely believed to be one of the cornerstones of personal and social success (Forgas and Williams, 2003). According to Freud theory, the self is developed as the result of the conflict between id, ego and superego (Bakhurst and Sypnowich, 1995). Chapter 2 discusses the development of the self as the result of comparing the self-concept of who the person thinks he is and the possible selves as images of what the person dreams of or dreads becoming in the future. Within the social identity approach, the self is taken to comprise both personal and social identity. The developmental study of the social self is important because social identities of adults mobilize specific forms of group-related perception and actions. The understanding of the relation between social self-conceptions and social action becomes vit ally important because social identity creates and defines the individual’s place in the society. ... uch actions as supporting person’s dreams, strengthening positive self-image and inspiring for further improvements have profound and long-lasting impact. By helping people connect to their sense of optimism and individual vision of ideal self, people can highly motivate and energize others for better learning, development and change (Bennett and Sani, 2004). The main idea of the self discussed in Chapter 2 is that usually people tend to overestimate of what others think about them, thus, their behavior is limited and controlled by fear, lack of confidence and social stereotypes. When people speak in public, for instance, they usually feel nervous and think it is obvious for others. Though, if to explain about spotlight effect and the illusion of transparency (informed condition), people become more confident while speaking in public and felt better about their speech and appearance than those in the control and reassurance conditions. The development of the self starts at the early age when children learn to understand themselves through the perception of surrounding world and in relation to certain social groups. In the process of developing a theory of mind, children and adolescents gradually learn that people have thoughts, feelings, motives and behavior different from their own. The interpersonal skills are developed and nurtured through the relation to the family, friends, school mates, university mates, colleagues and other people (Bennett and Sani, 2004). Chapter 2 further discusses the sense of individualism and collectivism compared between industrialized Western cultures that have independent self and those in Asia, Africa, and Central and South America that have interdependent self. Such different perception of the self in these cultures creates different
