DNA and RNA are two examples of nucleic acids. These are biochemical entities that occur naturally. They are composed of sugar molecules, organic bases, and phosphate groups. If the sugar molecule contains ribose the nucleic acid formed is RNA; if the sugar molecule is a deoxyribose (missing one oxygen molecule) the nucleic acid formed is DNA.

A polymeric molecule composed of nucleotide monomers joined by phosphodiester bonds. These link the 5' ribose carbon atom of one nucleotide residue with the 3' ribose carbon atom of the neighbouring nucleotide residue, through a phosphate group. Each phosphate group ionises by losing a hydrogen ion thus becoming negatively charged, and giving the molecule its acidic character. The negative charge of nucleic acids is made use of in electrophoretic separations.
