Which base is a pyrimidine that is not found in RNA?

Explanation:
Pyrimidines are single-ring bases, and the ones you see in DNA and RNA are cytosine, uracil, and thymine. RNA uses cytosine and uracil, but thymine is reserved for DNA. Thymine differs from uracil by having a methyl group, a feature that helps stabilize DNA and supports its copying accurately. Since RNA incorporates uracil in place of thymine, thymine is not a component of RNA.
