Mechanism of Gene Transfer in Prokaryotes | Genetics
Article Shared by
In prokaryotes several mechanisms viz., transformation, conjugation and transduction have been described that mediate the formation of new recombinants. Transformation refers to transfer of relatively small segment of naked DNA from a donor cell (male) to the recipient (female) cell. Conjugation is the process of gene transfer between cells of opposite mating types that are […]
