Plasmids are extrachromosomal genetic element found in many bacteria and in a few eukaryotic cells. Plasmids are closed circles of double stranded DNA that can exist and replicate independently of the chromosome Plasmids provide genetic instructionsffor certain cell activities (e.g. resistance to antibiotic drugs). Plasmids are-Widely used as vectors to produce recombinant DNA for gene cloning.
