In [[RNA]] thymine is swapped for [[uracil]] to represent the same genetic information. In DNA, thymine (T) connects to [[adenine]] (A) by two [[hydrogen]] [[Chemical bond|bonds]]. These pair bonds hold the two strands of the DNA double helix structure together. == Other websites == * [http://www.compchemwiki.org/index.php?title=Thymine Computational Chemistry Wiki] {{Webarchive|url=https://web.archive.org/web/20060629143905/http://www.compchemwiki.org/index.php?title=Thymine |date=2006-06-29 }} {{multistub|chemistry|biology}} [[Category:Organonitrogen compounds]] [[Category:DNA]]
