Product Description
Mechanism of Action
Cytosine is a pyrimidine nucleobase that pairs with guanine via three hydrogen bonds in DNA and RNA. It is essential for genetic coding, information transfer and structural integrity of nucleic acids. Cytosine residues are central to epigenetic regulation through methylation, hydroxymethylation and deamination, which can alter gene expression and mutate sequences.
Benefits and Advantages
Used in DNA/RNA biochemistry, epigenetics research, base‑pairing studies, mutagenesis modelling, deamination pathway analysis and nucleic‑acid synthesis. Serves as a standard substrate for DNA repair and epigenetic enzyme assays.
Side Effects and Risks
Risks include mild irritation with dust exposure and potential mutagenicity in some derivative forms. Handle as a basic nucleobase with standard lab precautions.
