Discuss the main steps for protein synthesis

Expert Solution

Translation is the process of protein synthesis that uses mRNA which is product of transcription. The process is divided into three steps:

1. Initiation starts with smaller subunit of a ribosome combining with mRNA. The tRNA carrying the amino acid methionine forms a hydrogen bond with mRNA at the start codon, AUG. This is followed by joining of both units of ribosome along with the mRNA molecule. first tRNA binds with initiation codon of mRNA.

2. Elongation occurs when new tRNA carrying an amino acid binds at site of next codon at the ribosome.the codon is complementary to anticodon of tRNA. Ribosome joins the two amino acids together by a peptide bond. The ribosome then moves to the next codon and a new tRNA carrying an amino acid arrives at the ribosome and the cycle continues.

3. Termination occurs when the ribosome reaches one of the three stop codon i.e UAA or UGA or UAG.these stop codons do not have any corresponding tRNA. So rekease of chain starts with help of special factors.

At end all components of the complex separate.

Discuss in details, and in your own words, the steps of protein synthesis. This is a 20 point assignment so answers like "step 1 is transcription and step 2 is translation" are NOT acceptable. Make sure you go into details of each step and use your own words.

put the following processes of protein synthesis translation steps in the correct order : A- the next aa2-tRNA attach to the second codon on mRNA located in A site B- then large ribosomal subunit binds the small ribosomal subunit forming an active ribosome C- the ribosome breaks down and the mRNA dissociates and protein is released D- the ribosome small subunit binding to the mRNA F- the first amino acid moves to exit site and leaves the ribosome G- ribosome...

Question 2: Translation is another name for protein synthesis. There are three steps that take place repeatedly during elongation. a) Give the name and a short description of what happens during the first step of elongation during translation? b) Give the name and a short description of what happens during the second step of elongation during translation? C) Give the name and a short description of what happens during the third step of elongation during translation? Please help! Thanks

Translation can be considered to have three phases or steps: initiation, protein synthesis, and termination. Please give a detailed summary of the factors and molecules involved with each step and, where appropriate, compare/contrast the differences between prokaryotic and eukaryotic translation.
