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 at origin site
(c) these can shuttle between prokaryotic and
eukaryotic cells
(d) these often carry antibiotic resistance genes

Answer 1

Answer:

option B

Explanation:

Plasmids are small, self-duplicating, double-stranded, covalently closed and supercoiled, extra-chromosomal DNA circles, found in most species of bacteria and some species of yeasts. They have their own replication origin site, a selectable marker, and a restriction or cloning site. The insertion of foreign DNA at or near the cloning site neither inactivates the markers nor disrupts the replication of the plasmid.
