Uracil /ˈjʊərəsɪl/ (U) is one of the four nucleobases in the nucleic acid of RNA that are represented by the letters A G C and U. The others are adenine (A) cytosine (C) and guanine (G). In RNA uracil binds to adenine via two hydrogen bonds. In DNA the uracil nucleobase is replaced by thymine. Uracil could be considered a demethylated form of thymine.Uracil is a common and naturally occurring pyrimidine derivative.
