The second site is the P (polypeptide) site where the amino acid is moved from its TRNA to the growing chain of polypeptide. The third site is the E (exit) site where the empty TRNA stays before it is released back to the cytoplasm to combine with another amino acid and the process is repeated (Clancy and William, 2008).
The next phase in the translation process is the elongation phase. In this phase, the ribosome moves with the mRNA in a direction referred to 5’ to 3’ direction, which needs the elongation factor G. The tRNA that corresponds to the second codon bids to the site A, a step that requires the guanosine triphosphate (GTP), which provides energy for the process and the elongation factors EF-Tu and EF-Ts. After the TRNA- amino acid complex is in site A, GTP is broken down to form guanosine diphosphate (GDP) and released together with EF-Tu so as to be recycled by Elongation factor EF-Ts for the next process (Clancy and William, 2008).
The next process is the formation of peptide bonds between the first and second adjacent amino acid through the activity of peptidyl transferase. Once the peptide bond is formed, the ribosome translocates causing the tRNA to occupy the E site. The tRNA is released to the cytoplasm to combine with another amino acid. Additionally, the site A remains empty and is ready to accept the mRNA for the next codon. This process occurs repeatedly until all the codons in the mRNA are read by the TRNA molecules, and the amino acids attached to the tRNA are joined to the chain of the growing polypeptide in the appropriate order. As soon as this takes place, translation process is terminated; the nascent protein is released from the ribosome and the mRNA (Clancy and William, ...Download file to see next pagesRead More

There are many ways in which protein concentrations in substances, particularly solutions, can be determined. The most common approach is the application of a regression analysis model to develop a relationship between protein concentration in a solution and absorbance rate that can be experimentally determined.

Examine the structure and function of proteins
Biotechnology entails understanding,exploiting,and modifying proteins for useful purposes.In order to accomplish this, one needs to understand various fuctions of proteins and their structure.The focus of this paper is to summarize various structures of proteins,various funcions of protein molecule in the cell, the link between molecular structure of proteins and their function,and how proteins as a whole contribute to health and/or disease.

About Genes. DNA is the basic form in which instructions and information on the characteristics of any organism is stored in the cells. This information and instructions for the synthesis of the proteins is stored in DNA molecule in form of a sequence of nucleotides, including Adenine, Thymine, guanine and cytosine; commonly abbreviated as A, T, G and C respectively, in a given order.

How proteins in the diet are disassembled and then reassembled to form useful proteins in the body
Disassembly of proteins is also called as proteolysis. First of all, proteins in our food are broken down into smaller units called as peptide chains. Many digestive enzymes include pepsin, trypsin, elastase and chymotrypsin. These peptides are further converted into amino acids by various proteolytic enzymes.

Mutation is generally accepted by the scientific community as the mechanism upon which natural selection acts, providing the advantageous new traits that survive and multiply in offspring or disadvantageous traits that die out with weaker organisms. Changes in DNA caused by mutation can cause errors in protein sequence, creating partially or completely non-functional proteins.
