उत्तर १
Plasmid is a circular, double stranded, self-replicating, extra-chromosomal DNA molecule.
उत्तर २
Plasmids are small, circular and duplex DNA molecules and their natural function is to confer antibiotic resistance to the host cell. They have several properties that make them extremely useful as cloning vectors.
