    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 25 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 :

     UAA is the stop codon. Therefore at 25th amino acid the synthesis of polypeptide stops. So, a polypeptide of 24 amino acid is formed.
