No recombination between plasmids was observed after conjugal transfer of a plasmid into a cell carrying another plasmid. Two types of such recombination took place after transformation, one type being Rec+ dependent and suggesting a preferred site of recombination. The other much rarer type was at least partially Rec+ independent.

Objetivo. O presente trabalho objetivou conhecer a relação entre valores humanos e crenças sobre violência conjugal. Método.

In previous studies we identified an 18-kb region of the Bacteroides conjugative transposon CTnDOT that was sufficient for mobilization of coresident plasmids and unlinked integrated elements, as well as self-transfer from Bacteroides to Escherichia coli. When this 18-kb region was cloned on a plasmid (pLYL72), the plasmid transferred itself constitutively in the absence of a coresident conjuga...

The genetic and biochemical properties of an endonuclease mediated by the mutagenesis-enhancing plasmid pKM101 have been investigated. Taking advantage of the observation that this endonuclease, unlike host-coded DNases, is active in the presence of EDTA, we have developed an assay with nondenaturing acrylamide gels containing DNA. We have localized the plasmid DNA sufficient for nuclease expre...
