WitrynaPhosphodiesters. A phosphodiester bond occurs when two of the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. Phosphodiester bonds are central to all life on Earth, [fn 1] as they make up the backbone of the strands of nucleic acid. In DNA and RNA, the phosphodiester bond is … Witryna20 lis 2024 · The RNA is destroyed. (Right) DNA has a hydrogen atom (red) circle in the same location of the hydroxyl group in RNA. Hydrogen does not promote this hydrolysis. This is why RNA (and the mRNA vaccines) are unstable and must be kept cold. So, it really just comes down to this: DNA differs from RNA by one oxygen atom …
