DNA is (deoxyribonucleic acid) Is a self-replicating material. It is present in almost every living organism, as the primary constituent of chromosomes. It is the carrier of genetic organisms.

DNA is made up of molecules that are called nucleotides. Each nucleotide contains a phosphate group(a sugar group and a nitrogen base) The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
