Deoxyribonucleic acid (DNA) is a molecule made up of two polynucleotide chains that coil around each other to form a double helix and carry genetic instructions for all known organisms and viruses' formation, function, growth, and reproduction. Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four major types of macromolecules that are required for all known forms of life, alongside proteins, lipids, and complex carbohydrates (polysaccharides).
