The F' plasmids ORF-1 (purE+ tsxs proC+ lac+) and F'14 (argE+ metB+ ilv+) contain active regions of recombination, fre I and fre II correspondingly. The plasmid ORF-1 is stable in recF- cells (i.e., with the RecBC pathway of recombination) and decays in rec+ cells (RecBCF pathway) giving two types o
