WebIn the mid-1950s, the physicist George Gamow extended this line of thinking to deduce that the genetic code was likely composed of triplets of nucleotides. That is, he proposed that a group of 3 3 successive nucleotides in a gene might code for one amino acid in a polypeptide. Gamow's reasoning was that even a doublet code ( 2 2 nucleotides per ... WebThe defining feature of an amino acid is its side chain (at top, blue circle; below, all colored circles). When connected together by a series of peptide bonds, amino acids form a polypeptide ...
