R plasmid
resistance plasmid a conjugative factor in bacterial cells that promotes resistance to agents such as antibiotics, metal ions, ultraviolet radiation, and bacteriophage. R plasmids are large with two functionally distinct parts: a resistance transfer factor (RTF), consisting of genes for autonomous replication and conjugation; and a resistance determinant (R determinant) containing the genes for resistance (R genes); called also R factor.
