DNA is made up of sugars, phospate groups, and nitrogenous bases and its shape is a double helix. The complementary structure the two strands of DNA allow each strand to serve as a template during replication.

DNA is made up of molecules 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). The order of these bases is what determines DNA's instructions, or genetic code.
