There are also purines and pyrimidines in RNA, but since it is single-stranded, they are not bonded in base pairs. There are two types of purine and three types of pyrimidine. The purines are ...

The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...

To multiply rapidly, cancer cells need to quickly manufacture DNA and RNA, which requires sufficient quantities of purines and pyrimidines. Upon analyzing the levels of 3,000 genes in a T cell ...

which is also slowed in the absence of water to react with the pyrimidine bases. At the heart of it, water can be seen as the main reason that, traditionally, DNA (or RNA) must be stored with ...
