Question

What is conjugation? Who discovered it and in which organism?

Accepted Answer

Conjugation is a type of sexual reproduction occur in bacteria and certain filamentous algae. Transfer of genetic material from one cell into another cell through the conjugation tube is called conjugation. During this process, one bacterium serves as the donor of the genetic material, and the other serves as the recipient. The donor bacterium carries a DNA sequence called the fertility factor, or F-factor.

The process of conjugation was discovered by Nobel Prize winners Joshua Lederberg and Edward Tatum in E. Coli bacterium. These scientists showed that the Escherichia coli bacterium enters a sexual phase during where they could share genetic information.
