The so-called disparity mutagenesis technique selectively elevates mutation in the lagging strand of DNA by using a mutant form of DNA polymerase δ, encoded on a proofreading-deficient pol3 gene. This novel mutagenesis technique generates a pool of mutants that includes a no-mutant strain together with mutant strains carrying multiple mutations. By using a suitable screening system it is possible to isolate the desired mutant strain from this pool of mutants. Here, we used our novel mutagenesis technique to isolate a yeast strain with good growth characteristics that was glycosylation deficient.
