Cytidine is essential for studying RNA structure and function, serving as a precursor for mRNA and tRNA synthesis. It is used in cell culture media to support nucleotide metabolism in proliferating cells. Researchers also employ cytidine derivatives to investigate epigenetic modifications, such as DNA methylation, and to develop antiviral or anticancer therapeutics targeting nucleic acid pathways.
