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 ...

Which RNA base bonded with thymine - answers.com
thymine does not exist on mRNA or tRNA strands, it is replaced by a base called uracil. however, a thymine on a DNA strand being replicated in protein synthesis will bond with an adenine base.
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 between consecutive bases along the nucleotide chain in the vicinity of their carbon–carbon double bonds. The dimerization reaction can also occur among pyrimidine bases in dsRNA (double-stranded RNA)—uracil or ...
Molecular Biology of the Cell - Thymine vs. Uracil
Thymine vs. Uracil We all know from high school bio that thymine takes the place of uracil in DNA. But why exactly does this occur? What advantage does thymine offer over uracil? When I asked a...
Pearson - The Biology Place
Concept 6 Review DNA and RNA Bases. In DNA, there are four different bases: adenine (A) and guanine (G) are the larger purines. Cytosine (C) and thymine (T) are the smaller pyrimidines.
