Question:medium

Given below are two statements: Assertion (A): The completion of polypeptide synthesis is signaled by the translocation of one of the stop codons into the A site. Reason (R): There are no t-RNA that recognize these codons under normal circumstances, termination of the chain does not involve the binding of a t-RNA.

Show Hint

Stop codons do not code for amino acids and are not recognized by tRNA. They are recognized by release factors during translation termination.
