During induction, a piece of the host cell chromosome comes off with the prophage. This DNA is transferred to the recipient cell. The lambda phage of Escherichia coli is often used to demonstrate specialized transduction. Episome - A plasmid that can exist autonomously or integrated. Gives the bacterium the ability to mate.
Special pili are present.
If the F factor has a piece of the chromosome attach to it, it is a F prime cell. F plus and F minus matings. An F factor is transferred from F plus to F minus. Only one of the DNA strands of the plasmid is actually transfered, but it is immediatly transferred. Hfr and F minus matings.
