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.
DNA Definition. DNA is the acronym for deoxyribonucleic acid, usually 2'-deoxy-5'-ribonucleic acid. DNA is a molecular code used within cells to form proteins. DNA is considered a genetic blueprint for an organism because every cell in the body that contains DNA has these instructions, which enable the organism to grow, repair itself, and reproduce.
