Disclosed is a significantly improved synthetic method of producing a set of mutagenized progeny polynucleotides which contain at least one substituted codon encoding for each of the 20 naturally encoded amino acids or any selected subset thereof. This in turn, similarly provides a method for producing from a parental template polypeptide, a set of mutagenized progeny polypeptides in which all 20 naturally encoded amino acids is represented at each original amino acid position or any selected subset thereof. The methods described herein enable the synthesis of defined, complex mixtures of oligonucleotides, in instances where the incorporation of degenerate bases is impractical. These oligonucleotide mixtures are useful for a variety of applications such as recombination methods, site-saturation mutagenesis, or the like. |
