Molecular studies in yeast often require the isolation of both plasmid and chromosomal yeast DNA. Plasmid DNA is used in the transformation of E. coli, whereas chromosomal DNA is used for Southern hybridization analysis, in vitro amplification by the polymerase chain reaction (PCR), or cloning of integrated plasmids. This unit presents two variations of the “smash and grab” protocol that produce suitable DNA for all these applications. These protocols work for both Saccharomyces cerevisiae and Schizosaccharomyces pombe.
