Conjugation is a mechanism of horizontal gene transfer as are transformation and transduction, although these two other mechanisms do not involve cell-to-cell contact. Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell to cell contact or by a bridge-like connection between two cells. 3. Conjugation occur by physical contact between cells. The cell which transfer plasmid is called donor and the cell which receive the plasmid is called recipient. The cell which has received the plasmid from the donor cell is called trans-conjugant. The phenomenon of conjugation in bacteria was discovered by laderburg and Tatum in 1946. Conclusions Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell- to-cell contact or by a bridge-like connection between two cells; it is regarded as the bacterial equivalent of sexual reproduction or mating since it involves the exchange of genetic material. Transduction uses bacterial viruses, called bacteriophages, to transfer DNA from one infected cell to another. Transformation is the ability of some cells to take up freely floating DNA found in Bacterial Conjugation. Bacterial conjugation is one of the principal means of dissemination of genetic information among microbes and from bacteria to other domains of life including plants and other eukaryotes.

Related terms: Plasmid; Nested Gene; Bacterium; Conjugation; Mutation; Bacteriophage Bacterial conjugation is a sexual mode of genetic transfer in the sense that chromosomal material from two sexually distinct types of cells are brought together in a defined and programmed process. In conjugation, DNA is transferred between bacteria through a tube between cells. This tube formed between both cells (i.e., the donor and recipient bacterial cell) is known as sex pilus or just pilus. Bacterial conjugation is a sexual mode of genetic transfer in the sense that chromosomal material from two sexually distinct cell types is brought together in a defined and programmed process. However, in bacterial conjugation, the process involves only a portion (usually small) of the genome of one of the cells (the donor) and the complete Conjugation is one the three mechanism of DNA exchange between bacteria, the other being transformation and transduction. Conjugation occurs between two living cells, involves cell to cell contact, and requires mobilization of either a plasmid or a chromosome of donor bacterial cells. Bacterial conjugation and transfer of F plasmid. The process of bacterial conjugation is based on the principle that the plasmid or any other genetic material is transferred from the donor cell to the recipient cell through close physical contact. Of all the conjugative plasmids, the F (fertility) plasmid of E. coli was the first discovered and is one of the best-studied. Bacterial conjugation is a way by which a bacterial cell transfers genetic material to another bacterial cell. The genetic material that is transferred through bacterial conjugation is a small plasmid, known as F-plasmid (F for fertility factor), that carries genetic information different from that which is already present in the chromosomes of the bacterial cell.
