    A functional piece of mRNA has 66 codons. What is the maximum number of amino acids that could be present in the protein coded for by this mRNA?

    A) 22                                

    B) 64    

    C) 65        

    D)        66

    Correct Answer: C

    Solution :

    [c] A functional strand of mRNA must have a start and a stop codon. The start codon of- ten also codes for the amino acid methionme, which may or may not end up being a part of the final protein. However, the stop codon would not code for an amino acid. Thus, with 66 codons in the mRNA, there could be as many as 65 amino acids in the protein product.
