उत्तर
A cloning vector should have a replication origin that allows it to reproduce itself within the host cell. It should include a restriction site for the insertion of the target DNA. It should include a selectable marker with an antibiotic resistance gene to aid in the screening of the recombinant organism. By taking into account all of the above, She should select Vector-C.
