Question

besides nucleus DNA is also present in​

Answer 1

Extrachromosomal DNA is any DNA that is found outside the nucleus of a cell. It is also referred to as extranuclear DNA or cytoplasmic DNA. ... In prokaryotes, nonviral extrachromosomal DNA is primarily found in plasmids whereas in eukaryotes extrachromosomal DNA is primarily found in organelles.

Answer 2

Besides nucleus DNA is also present in the cell cytoplasm, mitochondria, plastids, and as a plasmid.

• DNA (Deoxyribonucleic acid) is present in the nucleus as a genetic material of a cell.
• But besides the nucleus, it is also present in semi-autonomous organelles of the cell named mitochondria and plastid.
• In bacterial cells, besides the core genome, DNA is also present as a plasmid.
• In mitochondria, there is circular, closed, and double-stranded DNA which contains approx 16,500 base pairs.
• In plastid, DNA is double-stranded and circular with 120kb-170kb.
• Plasmid is an extra-chromosomal, self-replicating DNA, which is present in a bacterial cell.
