    Instead of 3, if 2 bases code for an amino acid, The degeneracy of codons coding for the same. Amino acid would have:

    A) Increased

    B) Decreased

    C) Remained the same

    D) Been uncertain

    Correct Answer: B

    Solution :

    [b] If 2 bases code for an amino acid, there are \[{{4}^{2}}\] or 16 possible combinations that will code for 20 different amino acids. So, same amino acid will be coded by one codon only, that is, degeneracy of codons decreases.
