Where are plasmids found?

Explanation:
Plasmids are extrachromosomal, small circular DNA molecules that occur mainly in bacteria. They replicate independently of the bacterial chromosome and reside in the cytoplasm as separate DNA circles. Because bacteria lack a true nucleus, plasmids aren’t located in a nucleus. While mitochondria and chloroplasts do contain their own DNA, that DNA is the organelle’s genome, not a plasmid, which is a distinct, extra piece of DNA found in many bacteria. Plasmids are widely used in genetic engineering as vectors to carry foreign genes.
