title: Multiple, tandem plasmid integration in Saccharomyces cerevisiae.
abstract: Nonreplicating plasmids transform Saccharomyces cerevisiae by recombining with a homologous site in the genome. Frequently, multiple copies of the plasmid integrate in a tandem array. We show that, after transformation with restriction enzyme-cut plasmids, most, if not all, multimers arise by sequential integration of plasmid molecules into the same genomic location.
