Researchers extend human epigenomic map

Ten years ago, scientists announced the end of the Human Genome Project, the international attempt to learn which combination of four nucleotides—adenine, thymine, cytosine, and guanine—is unique to homo sapien DNA. This ...

Search for epigenetic decoder leads scientists to Rett Syndrome

(Medical Xpress)—A few years ago, scientists discovered an unexpected layer of information woven into the genetic code – a nucleotide called 5-hydroxymethylcytosine, or 5hmC. Its meaning was unknown at the time, but a ...

Cytosine

Cytosine (C) is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2). The nucleoside of cytosine is cytidine. In Watson-Crick base pairing, it forms three hydrogen bonds with guanine.
