Q. Plasmid 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
Explanation
Plasmid is an extrachromosomal genetic of DNA that is capable of replicating independently of host chromosome. It forms the basis of many cloning vectors used in genetic engineering
