DNA is Deoxyribonucleic Acid. It is the genetic material in maximum of the organisms. The DNA is a polymer made from nucleotides (sugar, nitrogenous bases and phosphate group). It is composed of two strands of phosphate and sugar backbone in an antiparallel direction. The nitrogenous bases present in DNA are Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).
