Here we describe the results of an X-ray diffraction analysis of crystals of N 1-methyl cytosine. The presence of the methyl group makes it likely that the molecule has the same tautomeric form as ...

Some examples of genetic diseases linked to cytosine mutations include: Sickle cell anemia: A single C-to-T mutation in the beta-globin gene leads to the production of abnormal hemoglobin, causing red ...
