Marshall Nirenberg and his colleagues deciphered the genetic code in the early 1960s. Their experimental strategy involved constructing RNA templates by using various ribonucleotides and polynucleotide phosphorylase, an enzyme that links available nucleotides together in random order, followed by expression from the templates using a cell-free translation system. This experimental strategy was used to synthesize poly(UA). Because the polymerization of nucleotides by polynucleotide phosphorylase is random, all possible codons containing U and A could occur in the RNA template.
