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. what amino acids would be incorporated into a protein when poly(UG) is used as a template
