However, a triplet code produces 64 (4 3 = 64) possible combinations, or codons. Thus, a triplet code introduces the problem of there being more than three times the number of codons than amino acids.

Nirenberg's Genetic Code Chart, 1961-66 On May 27, 1961, Heinrich Matthaei, a postdoc working with NIH scientist Marshal Nirenberg, placed synthetic polyuracil RNA into 20 test tubes to see what it ...

Thus, early researchers quickly determined that the smallest combination of As, Cs, Gs, and Us that could encode all 20 amino acids in RNA would be a triplet (three-base) code. A triplet ...
