AIIMS November 2011 – MCQ 2

If 4 nucleotide repeats code for a amino acid, what is maximum number of amino acids possible?
A. 16
B. 64
C. 4
D. 256

Correct answer : 256

A codon with 3 nucleotides can code for upto 64 amino acids, whereas a codon with 4 nucleotide repeats can code for upto 256 amino acids. For this to be possible, the stop codon should also code for an amino acid like the start codon coding for methionine.
