Nucleobases are the parts of nucleic acids (DNA and RNA) that are involved in pairing of the two strands. The primary nucleobases are cytosine, guanine, adenine (found in both DNA and RNA), thymine (found only in DNA) and uracil (found only in RNA), abbreviated as C, G, A, T, and U, respectively. There are many additional nucleobases, usually derived from the primary ones.
