Deoxyribonucleic acid or DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce. These instructions are found inside every cell, and are passed down from parents to their children.
DNA structure. 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.
The DNA molecule has a backbone of sugars and phosphate groups off of which hang simpler units called nucleotide bases. DNAcontains only four bases, called A, T, C and G. ... The four roles DNA plays are replication, encoding information, mutation/recombination and gene expression.
