What is conjugation????

It is a mode of reproduction. It is a mating process where the temporary union of two one celled organisms results in the exchange of genetic material. It includes any of various sexual processes in microorganisms in which gene transfer follows the establishment of direct contact between two (or more) cells.

In bacterial conjugation, one bacterium (the "male" or donor cell) transfers DNA to another (the "female" or recipient cell) while the cells are in physical contact. A recipient that has received DNA from a donor is called a transconjugant.

Conjugation is seen in bacteria, ciliate protozoans, certain algae and fungi.
