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.
Conjugation is the process by which a plasmid is transferred from an F+ cell into an F-cell. The F factor in the F+ cell contains genes which express pili for attachment, and special membrane proteins for the transfer complex. Some conjugative plasmids carry drug resistant strains--a big problem for hospitals.
