Show transcribed image text Why does DNA contain thymine as a pairing base with adenine, but in the transcription, RNA contains uracil instead of thymine.A series of 1,6-bis[(benzyloxy)methyl]uracil derivatives combining structural features of both diphenyl ether and pyridone types of NNRTIs were synthesized.A process for the preparation of 5-(trifluoromethyl)uracil has now been found which is characterised in that. a) The thymine (=5-methyl-uracil).Structural Biochemistry/Nucleic Acid/Nitrogenous Bases/Pyrimidines/Uracil. Uracil is planar and it readily pairs with adenine because the methyl group.Re: Why does uracil replace thymine in RNA?

Thymine was first isolated (from calves thymus glands) in 1893 by Albrecht Kossel and Albert Neumann.Uracil is well known as one of the bases used in RNA, but why is it not used in DNA - or is it?
