A good cloning vector should NOT have:
A) an origin of replication.

D) a small size.
E) genes allowing its insertion into the host chromosome.

Question

Quizplus · Accepted Answer

A good cloning vector should be easily maintained in a host, which typically requires an origin of replication, an antibiotic resistance gene for selection, several unique restriction sites for the insertion of foreign DNA, and a small size to facilitate entry into host cells. Genes that allow for the insertion of the vector into the host chromosome are not necessary and can complicate the cloning process.
