Use

Cytosine is first isolated by hydrolysis of calf thymus tissue by Albrecht Kossel (1853–1927) and A. Neumann during 1893–1894. Thymine’s structure was published in 1900 and confi rmed over the next several years when it was synthesized by several investigators. In 1903, cytosine was synthesized by Henry Lord Wheeler (1867–1914) and Treat B. Johnson, confirming its structure. Uracil was first isolated in 1900 from yeast nucleic acid found in bovine thymus and herring sperm.the methylation of uracil produces thymine; thymine is also called 5-methyluracil because methylation takes place at the fi fth carbon in uracil to produce thymine.
