what is dna


DNA is a molecule composed of two polynucleotide chains that coil around each other to form a double helix. 1 It carries genetic information for the development and functioning of an organism. 2 1 DNA is essential for all known forms of life, alongside proteins, lipids and complex carbohydrates. 3 It contains units of biological building blocks called nucleotides and contains our hereditary material and our genes, the things that make us unique. 2
