The hydrolytic step leading to the release of a polypeptide chain from a ribosome is catalysed by `:`

A

UAA

B

release factors

C

step codons

D

peptidyl transferase

Text Solution

Verified by Experts

The correct Answer is:
D
When a stop codon is reached, such as UAA, UGA or UAG, aminoacyl t-RNA does not bind to the A site of a ribosome. Instead of forming a peptide bond, peptidyl transferase catalyses the hydrolytic step that leads to the release of newly synthesized proteins.
