The genetic material that is transferred through bacterial conjugation is a small plasmid, known as F-plasmid (F for fertility factor), that carries genetic information different from that which is already present in the chromosomes of the bacterial cell. Conjugation occurs between two living cells, involves cell to cell contact, and requires mobilization of either a plasmid or a chromosome of donor bacterial cells..
