Explain sexual reproduction in bacteria?
Bacteria can not reproduce sexually, yet they exhibit genetic recombination in three ways: (i) Conjugation: Lederberg and Tatum discovered it. The presence of a plasmid called F-factor in cells identifies the donor or male call. The donor cell has hollow cylindrical sex Pilli that adhere to the recipient bacteria. With the help of sex pilli, the donor and receiver make physical contact. The recipient cell receives a plasmid or a plant of donor DNA. (ii) Griffith was the one who discovered it. It includes the death of a bacterial donor cell, which causes its DNA to be released into the external media, where it is broken and integrated into metabolically active cells. Recombination occurs when a recipient cell incorporates donor DNA and expresses all of its characteristics alongside those of the donor cell. (iii) Zinder and Lederberg were the first to discover transduction. A virus is used to deliver donor genes to the recipient. A phage promotes bacterial lysis and integrates bacterial genes into phages before being released and infecting additional bacterial genes.
