Thymine - Wikipedia
Thymine / ˈ θ aɪ m ɪ n / (T, Thy) is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine.Thymine is also known as 5-methyluracil, a pyrimidine nucleobase. In RNA, thymine is replaced by the nucleobase uracil.Thymine was first isolated in 1893 by Albrecht Kossel and Albert Neumann from calves ...

The bases are often referred to as A, C, G and T, the initials of their full chemical names, adenine, cytosine, guanine and thymine. — The Economist, "BiotechnologyGene editing takes another step forward," 26 Oct. 2017
Pyrimidine dimer - Wikipedia
Pyrimidine dimers are molecular lesions formed from thymine or cytosine bases in DNA via photochemical reactions. Ultraviolet light (UV) induces the formation of covalent linkages by reactions localized on the C=C double bonds. In dsRNA (double-stranded RNA), uracil dimers may also accumulate as a result of UV radiation. Two common UV products are cyclobutane pyrimidine dimers (CPDs, including ...
