Two bacteria exchange genetic material
WebBacterial Conjugation. Conjugation is the method of transfer of genetic material from one bacteria to another placed in contact. This method was proposed by Lederberg and Tatum. They discovered that the F-factor can … WebBacterial Conjugation. Bacterial conjugation is a process through which genetic material is shared between two different bacteria. The technique is an evolutionary advantage in that it allows for the fitness of a given gene to increase if the recipient of the plasmid is more able to continue the genetic lineage.
