DNA is made up of nucleotides that contain a sugar, phosphate, and one of four nitrogenous bases (adenine, thymine, guanine, cytosine). The nucleotides are connected in a double helix shape by hydrogen bonds between the bases, with adenine bonding only to thymine and guanine bonding only to cytosine. Studying DNA is important for disease diagnosis and treatment, determining paternity, forensics, and agricultural applications.
