Conjugation is the direct transfer of DNA from one bacterium to another.
Bacteria can exchange genetic information through three different mechanisms; conjugation, transduction, and transformation. Bacterial conjugation involves the transfer of a plasmid from one bacterium to the other, through cell-to-cell contact. Bacterial transduction is performed through bacteriophages. Bacterial transformation refers to the process of moving genetic elements to various positions of the genome.
