    I think it's 146 as three bases code for an amino acid. (obviously 438/3=146)

    If I'm wrong, I'm so sorry I'll blame it on my tiredness.

    Hi OP,

    If three bases make up a codon (triplet of bases) and one codon codes for ONE amino acid, the calculation really is quite simple.

    So,what calculation do you think you would need to carry out?


    *Already beaten to it! The answer is (as said above) 146 amino acids! (438/3=146).

    The question should really say 438 coding bases, as genes almost always contain non-coding DNA too.

    But Changing Skies and TheStudent18 are correct. Remember base triplets form a codon which codes for one amino acid
