Which statement is correct about plasmid cloning vectors?

Answer and explanation

Correct answer: They can be small, circular DNA carriers

Plasmid cloning vectors are usually small, circular DNA molecules that carry a foreign DNA fragment into a host cell. They contain an origin of replication, allowing them to make copies inside the host. Restriction enzymes cut DNA, but they are not vectors. Exam tip: Identify a cloning vector by clues such as circular DNA, an origin of replication, and a selectable marker.
