tsütosiini

Tsütosiini is one of the four main nucleobases found in DNA and RNA. Its chemical formula is C4H5N3O and it is a pyrimidine derivative. In DNA, tsütosiini always pairs with guaniini through three hydrogen bonds. This complementary base pairing is fundamental to the structure and function of the genetic material. In RNA, tsütosiini also pairs with guaniini. Tsütosiini plays a crucial role in heredity and the transmission of genetic information from one generation to the next. It is synthesized in the body through a complex metabolic pathway. Mutations involving tsütosiini, such as deamination or oxidation, can lead to changes in the genetic code and potentially cause disease. The study of tsütosiini and its interactions is a cornerstone of molecular biology and genetics.
