Nucleic acids are the molecules inside the cell that store and process genetic or hereditary information. The two types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). These macromolecules are called nucleic acids, because they were first found inside the nucleus of the cell. The monomers that make up nucleic acids are called nucleotides. Each nucleotide contains a sugar, a base, and a phosphate group.
