WebMar 1, 2024 · The purines in DNA are adenine and guanine, the same as in RNA. The pyrimidines in DNA are cytosine and thymine; in RNA, they are cytosine and uracil. Purines are larger than pyrimidines because they have a two-ring structure while pyrimidines only have a single ring. You should now feel confident in your ability to identify and … WebApr 4, 2024 · It is believed that thymine replaced uracil (the RNA base) in DNA because of the deleterious effects of slow spontaneous deamination of cytosine to uracil: by employing thymine instead of uracil, any uracil in DNA would clearly be aberrant, allowing a specific mechanism of repair (involving uracil DNA glycosylase) to evolve with impunity.

Nucleobases, also known as nitrogenous bases or often simply bases, are nitrogen-containing biological compounds that form nucleosides, which, in turn, are components of nucleotides, with all of these monomers constituting the basic building blocks of nucleic acids. The ability of nucleobases to form base pairs and to stack one upon another leads directly to long-chain helical structures such as ribonucleic …
