how do initiation and termination of translation occur in a bacteria ?
Dear student,
Please find below the solution to the asked query
Translation is the process of polymerisation of amino acids for protein synthesis from mRNA. The steps involved are:
1. Activation of amino acids by ATP
2. Charging of tRNA
3. Formation of polypeptide chain:
There are 3 steps in this:
a. Chain Initiation: It involves binging of mRNA with small subunit of ribosome, then binding with tRNA carrying f-methionine and then attachment to the large subunit of the ribosome.
b. Chain elongation: A site is produced next to P site. A new aminoacyl tRNA reaches the A site and forms a bond. Elongation factors and GTP is required. A peptide bond is formed. And the process continues till termination codon is reached.
c. Chain termination; Once the termination codon is reached, release factors and GTP help in this process. The subunits of ribosome separate and amino acid chain is released.
