Is extra genomic DNA present in prokaryotes and eukaryotes? If yes, indicate their location in both the types of organisms.
Yes, extra genomic DNA is present in prokaryotes and eukaryotes.
• In eukaryotes, the extra genomic DNA is present in mitochondria and plastids.
• In many prokaryotic bacteria, small circular DNA called plasmids are present outside genomic DNA which helps the cell develop some phenotypic characteristics like resistance to anti-biotics.
