Answer by Lee Ifhar. Confidence votes 2. conjugation occurs between two bacterial cells and transfers DNA in the form of plasmids. this is one way to transfer of genetic material-it is not sexual reproduction, The other two ways to transfer genetic material between bacteria are transformation and transduction.
Thus, interspecies transfer of DNA by transduction is rare. Conjugation is the transfer of DNA by direct cell-to-cell contact that is mediated by plasmids (nonchromosomal DNA molecules). Conjugative plasmids encode an extremely efficient mechanism that mediates their own transfer from a donor cell to a recipient cell.
