Cell free protein synthesis also called in vitro protein synthesis , is the production of protein without the use of living cells. History The first elucidation of a codon was done by Marshall Nirenberg and Heinrich J. Matthaei in 1961 at the National Institutes of Health. They used a cell free system to translate a poly uracil RNA sequence or UUUUU... in biochemical terms and discovered that the polypeptide they had synthesized consisted of only the amino acid phenylalanine. They thereby deduced from this poly phenylalanine that the codon UUU specified the amino acid phenylalanine ref neur ref . Extending this work, Nirenberg and his coworkers were able to determine the nucleotide makeup of each codon Cell free systems in common use.
