F factor is fertility factor and it is defined as a factor which allows the genes to transmitted from one bacterial cell to the other by the process of conjugation. Not all bacterial cells have F factor present in them. The bacterial cell which has this F factor is designated as F+ whereas the one which lacks this is designated as F-.
This F factor has additional genetic material which otherwise is not found in the circular DNA of bacteria. It is known to be the first plasmid that was discovered and it belongs to the class of conjugative plasmids which play their role in controlling the functions that are related to sex in bacteria.
