The present invention is directed to a process for the production of a peptide. polypeptide. or protein having a predetermined property. In accordance with one embodiment. the process begins by producing by way of synthetic polynucleotide coupling. stochastically generated polynucleotide sequences. A library of expression vectors containing such stochastically generated polynucleotide sequences is formed. Next. host cells containing the vectors are cultured so as to produce peptides. polypeptides. or proteins encoded by the stochastically generated polynucle otide sequences. Screening or selection is carried out on such host cells to identify a peptide, polypeptide. or protein produced by the host cells which has the predetermined property. The stochastically generated polynucleotide sequence which encodes the identi? ed peptide. polypeptide. or protein is then isolated and used to produce the peptide …
