Description
Deoxyribonucleic acid DNA is a molecule composed of two chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid RNA are nucleic acids; alongside proteins, lipids and complex carbohydrates polysaccharides, nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life.
