Pyrimidine is group of molecules that are part of the DNA and RNA structure. These molecules feature a single ring structure made of six atoms.hen a sugar group is bound to a pyrimidine or a purine, it is called a nucleoside. Deoxycytosine and (deoxy)thymidine are the pyrimidine nucleosides and deoxyadenosine and deoxyguanosine are the purine nucleosides.
Pyrimidine dimers are molecular lesions formed from thymine or cytosine bases in DNA via photochemical reactions. Ultraviolet light 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 thymine dimers) and 6,4 photoproducts.
