(A) George Gamow,a physicist,was the first to propose that the genetic code must be a triplet of nucleotides. He reasoned that since there are only $4$ types of nitrogenous bases $(A, U, G, C)$ and $20$ amino acids to be coded,a single base $(4^1 = 4)$ or a doublet $(4^2 = 16)$ would not be sufficient to code for all $20$ amino acids. Therefore,a triplet code $(4^3 = 64)$ was necessary to account for all $20$ amino acids.

The assumption that the genetic code is a triplet was suggested by:
