Phosphodiester bond rotation
WebFeb 20, 2024 · Phosphodiester Bond is involved in the polymerization of nucleotides. When polymerization occurs, the -OH group gets attached to 3 carbon of nucleotides (sugar molecules) with the phosphate group’s -OH of another nucleotide. Hydrogen and hydroxyl may combine with each other. WebHow Do Nucleotides Join Together?

Phosphodiester bond rotation
Did you know?
In chemistry, a phosphodiester bond occurs when exactly two of the hydroxyl groups (−OH) in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. The "bond" involves this linkage C−O−PO−2O−C. Discussion of phosphodiesters is dominated by their prevalence in DNA and RNA, but phosphodiesters occur in other biomolecules, e.g. acyl carrier proteins. WebA.I. Cederbaum, in Liver Pathophysiology, 2024 Nucleic Acids. ROS cleave the phosphodiester bonds holding bases in RNA and DNA together and break the chain structure of RNA and DNA. ROS oxidize the purine and pyrimidine bases and prevent appropriate base pairing. The carbon 8 position of purines is a very sensitive site for …
