Nucleobases (or nucleotide bases/nitrogenous bases/aglycones) are the parts of DNA and RNA that may be involved in pairing (see also base pairs). The primary nucleobases are cytosine, guanine, adenine (DNA and RNA), thymine (DNA) and uracil (RNA), abbreviated as C, G, A, T, and U, respectively. They are usually simply called bases in genetics. Because A, G, C, and T appear in the DNA, these molecules are called DNA-bases; A, G, C, and U are called RNA-bases.
