Deoxyribonucleic acid or DNA is a chemical that contains nitrogen and is very important for living organisms. It plays and important role in making up the genetic constitution of the cell. It is hereditary and passes from one generation to another.
DNA is double stranded helix which coils and binds to non-histone proteins to pack inside the nucleus of the cell. Every living organism contains DNA or RNA as a genetic material.
