The sex factor F DNA transfer is mediated by f, the fertility factor F is a plasmid, a small self-replicating circle of DNA F carries genes that direct the formation of the conjugation tube and its replication and transfer to the recipient The F-factor replicates and a new copy is sent into the F- recipient cell. The F-factor is an example of a conjugative plasmidThe sex factor: F • DNA transfer is mediated by F, the fertility factor. • F is a plasmid, a small self-replicating circle of DNA. • F carries genes that direct the formation of the conjugation tube and its replication and transfer to the recipient • The F-factor replicates and a new copy is sent into the F￾recipient cell . The F-factor is an example of a conjugative plasmid
