Question:
Is extra genomic DNA present in prokaryotes and eukaryotes? If yes, indicate their location in both the types of organisms.
Solution:
Yes, extra genomic DNA is present in prokaryotes and eukaryotes. In organisms like bacteria in addition to the genomic DNA, there is a small circular DNA outside the genomic DNA. They are called plasmids. This is a unique phenotypic character to such bacteria.
In eukaryotes, the extra genomic DNA is present in two organelles- Mitochondria and plastids.
