DNA is a molecule composed of two polynucleotide chains that coil around each other to form a double helix.
It carries genetic information for the development and functioning of an organism.
DNA is essential for all known forms of life, alongside proteins, lipids and complex carbohydrates.
It contains units of biological building blocks called nucleotides and contains our hereditary material and our genes, the things that make us unique.

Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.
