A phosphodiester bond is formed between two sugar molecules and a phosphate group. This bond connects nucleotides, which form the backbone of a DNA or RNA chain.

A phosphodiester bond is formed between the primer and incoming dNTP, resulting in extension of the primer by a deoxynucleotide monophosphate (dNMP) and release of a pyrophosphate molecule. From: Reference Module in Life Sciences, 2020. Related terms: Peptide; Enzymes; Mutation; Proteins; Amino Acids; Introns; DNA; RNA • Phosphodiester bond A phosphodiester bond occurs when exactly two of the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. An example is found in the linking of two pentose (5 carbon sugar) rings to a phosphate group by strong, covalent ester bonds. The phosphodiester bond, which links the sugar molecules and phosphate molecules in the backbone, is one of the most crucial components for building DNA and RNA because it maintains the integrity of the genetic code and allows for life on this planet.

Native human DNA polymerase η, DNA and dATP were co-crystallized at pH 6.0 without Mg (2+). The polymerization reaction was initiated by exposing crystals to 1 mM Mg (2+) at pH 7.0, and stopped by freezing at desired time points for structural Under physiological conditions (pH ∼ 7) hydroxide ion catalysed cleavage of phosphodiester bonds is the predominant reaction mechanism (). 4 The 2′-oxyanion, which is deprotonated in a rapid pre-equilibrium step, attacks the adjacent phosphate group, resulting in formation of a dianionic pentacoordinated species.

From: Reference Module in Life Sciences, 2020 phosphodiester bond The chemical linkages that join up the sugar, base and phosphate NUCLEOTIDES of DNA and RNA into polynucleotide strands. The subunits of the strand are triphosphate nucleosides, but when a number of these join up (polymerize) under the action of the enzyme DNA polymerase, two of the phosphates are cleaved off leaving only one phosphorous atom between each pair of adjacent sugar molecules. Medical Definition of phosphodiester bond : a covalent bond in RNA or DNA that holds a polynucleotide chain together by joining a phosphate group at position 5 in the pentose sugar of one nucleotide to the hydroxyl group at position 3 in the pentose sugar of the next nucleotide — called also phosphodiester linkage A phosphodiester bond occurs when exactly two of the hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. An example is found in the linking of two pentose (5 carbon sugar) rings to a phosphate group by strong, covalent ester bonds.
