and a nitrogenous base. Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical bonds called phosphodiester bonds. Unlike DNA, RNA is usually single-stranded.

RNA, or ribonucleic acid, is a essential biological molecule that plays a crucial role in various cellular processes. It is a polymeric molecule composed of nucleotides, each containing a ribose sugar ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized chemically or isolated from ...
