In 125 amino acid sequence if codeon for` 25 ^`(th) amino acid is mutated to UAA , then

Options

A. A polypeptide of 24 amino acids is formed
B. A polypeptide of 124 amino acids is formed
C. No polypeptide are formed
D. A polypeptide of 25 amino acids is formed

Answer

A

Explanation

Each codon code for an amino acid if mutation occurs in `25^(th)` codon of amino acid then protein synthesis terminated because mutation lead to formation of stop codon UAA which lead for a polypeptide of 24 amino acid is formed
