Question

A gene encoding for a polypeptide of 60 amino acids get mutated at 30 th codon UAU becoming UAA The result would be, A polypeptide of 29 amino acids, Two polypeptides one with 29 amino acids and second with 31 amino acids., A polypeptide with 59 amino acids, A polypeptide of 25 amino acids.

In this example, 30 th codon is mutated to form stop codon. Thus the first 29 codons will be read and 29 amino acids will form a polypeptide chain. But the stop codon will not allow further translation to occur and the remaining codons will not be translated
