In this process, two cells of opposite mating type i.e., F + and F – become temporarily attached with each other by sex pilus (Fig. 2.26). The sex pilus has a hole of 2.5 pm diameter through which DNA can pass from donor to recipient cell. WebConjugation starts when two cells (donor (F+) and recipient (F-)) come into contact. This contact is established when the F pilus of the donor comes in contact with the cell surface of the recipient. In different species, pilus retraction has been observed in the absence of triggering events. sct mathias port viborg

WebConjugation, is a process by which genetic material is transferred from one bacterial cell (“donor cell” or “male cell”) to another (“recipient cell” or “female cell”) through a specialized intercellular connection called sex-pilus or conjugation tube. ADVERTISEMENTS: WebIn Gram-positive bacteria, the mechanism of conjugation is very different, as pili are not found, and no specific bridge between mating pairs of bacteria via a conjugative pilus is formed. At least two categories of conjugation that are mediated by self-transferable plasmids have been found.
