尿嘧啶
尿嘧啶(Uracil,简写U),是组成RNA的四种碱基之一。在DNA的转录时取代 DNA 中的胸腺嘧啶,与腺嘌呤配对。将尿嘧啶甲基化即得胸腺嘧啶 (T)。

Uracil 尿嘧啶
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 is a demethylated form of thymine.
