DNA stands for deoxyribonucleic acid and is a long chain of nucleotides. Each nucleotide is composed of a phosphate group, a sugar group, and a nitrogen-containing base. The four bases found in DNA are Adenine, Thymine, Cytosine, and Guanine.

Deoxyribonucleic acid (DNA) is a molecule that contains the instructions an organism needs to develop, live and reproduce. DNA is made of four different bases: adenine (A), thymine (T), cytosine (C) and guanine (G). DNA is organized into structures called chromosomes which are located inside the nucleus of a cell.

DNA molecules are so small that over one million of them can fit in a single drop of water. The human genome (the entire set of DNA) contains over 3 billion base pairs. The DNA molecule has two strands that are held together by weak bonds called hydrogen bonds.
