    How many pairs in the gene are needed to code for the enzyme, lysozyme, containing 129 amino acids found in egg white?

    A) \[3\text{ }\times \text{ }129\] base pairs

    B) \[\left( 3\times 129 \right)+\left( 3\times 3 \right)=396\]base pairs

    C) \[\left( 3\times 129 \right)+\left( 3\times 2 \right)=393\]base pairs

    D) 4\[\times \]129 base pairs

    Correct Answer: C

    Solution :

    [c] Three base pairs code for one amino acid and two more triplets are required for start and stop signals. \[\therefore \,\,\,\,(3\times 129)+(3\times 2)=393\]base pairs
