Convenient modification of the method for oligonucleotide-directed in vitro mutagenesis of cloned DNA

AbstractA new modification of the oligonucleotide-mediated mutagenesis technique has been developed. The proposed methodology has been used to produce specific base changes in the double-stranded plasmid DNA. For this purpose, special cloning vectors have been constructed using the synthetic oligodeoxyribonucleotides. The developed method allows the production of mutant DNA from those of the wild-type with a yield of 10–20%
