Cytosine biosynthesis
WebAug 14, 2024 · Cytosine methylation in genomic DNA has long been considered as one of the most important epigenetic mechanisms in most common eukaryotic cells [14, 15]. Cytosine methylation in genomic DNA plays an important role in regulating the expression of coding and non-coding genetic elements at the transcriptional and post-transcriptional … The biosynthesis of nucleotides involves enzyme-catalyzed reactions that convert substrates into more complex products. Nucleotides are the building blocks of DNA and RNA. Nucleotides are composed of a five-membered ring formed from ribose sugar in RNA, and deoxyribose sugar in DNA; these sugars are linked to a purine or pyrimidine base with a glycosidic bond and a phosphate group at the 5' l…
