Plasmids That Can Move Transposons from One Bacterial Cell to Another

Question

Plasmids that can move transposons from one bacterial cell to another are known as
A) conjugative R plasmids.
B) F plasmids.
C) Col plasmids.
D) Tn3 elements.
E) All of these

Accepted Answer

Conjugative R plasmids are known to carry transposons and can transfer them between bacterial cells through the process of conjugation. F plasmids and Col plasmids may carry antibiotics resistance genes but are not specifically associated with transposons. Tn3 elements refer specifically to a type of transposon and not to the plasmids that carry them, so D is also not the best choice. Therefore, A is the best answer as it specifically refers to plasmids that carry transposons and have the ability to transfer them through conjugation.
