While several checkpoints are well-studied in the eukaryotic cell cycle, much less is known about the cell cycle regulation in bacteria.
WebPlasmids replicate independently of the chromosomes and transmit genes that specify functions not essential for cell growth. One such function is conjugation, which takes place only in bacterial strains carrying the so-called F plasmid. (The strain Lederberg first used in his mating experiments in 1945 lacked this plasmid.)
