Polypeptide chain termination is enhanced by
Termination requires stop codon (UAA, UAG, UGA) and releasing factors .
Peptidyl transferase is also required which along with releasing factor hydrolyses peptide bond between tRNA at 'P' site and promotes the release of a newly synthesized polypeptide chain from ‘P’ site.
Stop codon
Peptidyl transferase
UAA
All of these
