This image illustrates the chemical structures of the five main nucleobases found in DNA and RNA. The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine ...

Both uracil and thymine pair with adenine ... In RNA, a point mutation can involve the substitution of uracil with another nucleobase, such as cytosine (C) or guanine (G). These mutations can ...

Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T ...

In 1992, researchers found that the amination reaction of sodium bisulfite with unmethylated cytosine is different than the reaction of sodium bisulfite with 5mC. Because of this difference, ...

During the process of transcription, DNA is converted to RNA, a complex molecule that is able to carry genetic information outside of the cell's nucleus. This page guides you through the ...
