Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.
Plant cell has nuclear (in nucleus)and extranuclear DNA. Extranuclear DNA is in its mitochondria and Chloroplasts.Mitochondria and chloroplasts are semiautonomous and it is because they have their own DNA, mRNA, tRNA, ribosomes and they replicate by binary fission so they are said to be self governing.
