Final answer:
Conjugation is the process by which genetic material is exchanged and united between two prokaryotic cells. DNA, usually in the form of plasmids, is transferred from a donor cell to a recipient cell, allowing for the exchange of genetic information.
Step-by-step explanation:
Conjugation is the process by which genetic material is exchanged and united between two prokaryotic cells, typically through the use of a pilus or mating bridge. During conjugation, DNA, usually in the form of plasmids, is transferred from a donor cell to a recipient cell. This process allows for the exchange of genetic information and can contribute to genetic variation in prokaryotes.
