Question
Chapter 28, Problem 28.37P
Interpretation Introduction
Interpretation:
In the codons of amino acid Leucine, the first and second bases are identical, the identity of the third base is irrelevant. For what other amino acid codons, the third base is irrelevant has to be given and for which amino acids they code has to be given.
