Question

how is the translation of mRNA termited

Answer 1

Termination

• Third codon shift to the A – site now at RNA charged with third amino acid binds at the A - site for chain elongation in the 5’ 3’ direction.

• When the aminoacyl tRNA reaches the termination codon like UAA, UGA and UAG termination of polypeptide chain of amino acids occurs.

• This leads to the release of the polypeptide chain of amino acids and tRNA from the ribosomes.

• The ribosomes dissociates into large and small subunit at the end of protein synthesis.
