    What would happen if in a gene encoding a polypeptide of 50 amino acids, 25th codon (UAU) is mutated to UAA?

    A) A polypeptide of 24 amino acids will be formed.

    B) Two polypeptides of 24 and 25 amino acids will be formed

    C) A polypeptide of 49 amino acids will be formed

    D) A polypeptide of 25 amino acids will be Formed

    Correct Answer: A

    Solution :

    [a] UAA is a nonsense codon. It signals for polypeptide chain termination. Hence, only 24 amino acids chain will be formed as the process of translation will be terminated at 25th codon.
