The Fertility factor (first named F by one of its discoverers Esther Lederberg) allows genes to be transferred from one bacterium carrying the factor to another bacterium lacking the factor by conjugation. The F factor is carried on the F episome, the first episome to be discovered. Unlike other plasmids, F factor is constitutive for transfer proteins due to the gene traJ. The F plasmid belongs to a class of conjugative plasmids that control sexual functions of bacteria with a fertility inhibition (Fin) system.

Famous quotes containing the words fertility and/or factor:
“Go bind thou up young dangling apricots
Which, like unruly children, make their sire
Stoop with oppression of their prodigal weight.
Give some supportance to the bending twigs.
Go thou, and like an executioner
Cut off the heads of too-fast-growing sprays
That look too lofty in our commonwealth.
All must be even in our government.
You thus employed, I will go root away
The noisome weeds which without profit suck
The soil’s fertility from wholesome flowers.”
—William Shakespeare (1564–1616)
“You factor in racism as a reality and you keep moving.”
—Jewell Jackson McCabe (b. 1945)
