Question

Plasmids are suitable vectors for gene cloning because (A) these are small circular DNA molecules which can integrate with host chromosomal DNA (B) these are small circular DNA molecules with their own replication origin site (C) these can shuttle between prokaryotic and eukaryotic cells (D) these often carry antibiotic resistance genes

Tardigrade Admin · Accepted Answer

Plasmids replicate autonomously. These carry a signal situated at their replication origin which determines how many copies are to be made and this number can be artificially increased for cloning of given gene.
