WebMay 23, 2024 · Conjugation is a mechanism whereby a bacterium can transfer genetic material to an adjacent bacterium. The genetic transfer requires contact between the two bacteria . This contact is mediated by the bacterial appendage called a pilus. Conjugation allows bacteria to increase their genetic diversity. WebIt contains genes that force recombination between the donor and recipient chromosomes. It degrades the chromosome of the recipient cell after conjugation. It allows auxotrophic bacterial cells to survive on minimal medium so that conjugation can occur. It contains genes necessary for replication of the donor's F plasmid.

WebThe F-plasmid belongs to a class of conjugative plasmids that control sexual functions of bacteria with a fertility inhibition (Fin) system. In this system, a trans-acting factor, FinO, and antisense RNAs, FinP, combine to repress the expression of the activator gene TraJ. TraJ is a transcription factor that upregulates the tra operon.

WebThere are special appendages present on bacterial cell surface which are called sex pilus or F pilus which forms the conjugation tube. The fertility (F) factor enables the cell to act as donor.
