Abstract

Delitto perfetto is a site-specific in vivo mutagenesis system that has been developed to generate changes at will in the genome of the yeast Saccharomyces cerevisiae. Using this technique, it is possible to rapidly and efficiently engineer yeast strains without requiring several intermediate steps as it functions in only two steps, both of which rely on homologous recombination to drive the changes to the target DNA region. The first step involves the insertion of a cassette containing two markers at or near the locus to be altered. The second step involves complete removal of this cassette with oligonucleotides and/or other genetic material and transfer of the expected genetic modification(s) to the chosen DNA locus. Here we provide a detailed protocol of the delitto perfetto approach and present examples of the most common and useful applications for in vivo mutagenesis to generate base substitutions, deletions, insertions, as well as for precise in vivo assembly and integration of multiple genetic elements, or gene collage.
