Deoxyribonucleic acid, or DNA, is a molecule that carries the genetic instructions for life in all living organisms, organized in a distinctive double helix structure made up of base pairs. It matters because it stores and transmits the biological information that determines the characteristics and functions of living things.

Deoxyribonucleic acid (; DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries 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.
