Phosphodiester bond The covalent bond joining the 3' hydroxyl of the sugar moiety of one (deoxy)ribo
nucleotide to the 5' hydroxyl of the adjacent sugar.
Full article >>>Phosphodiester bond. A bond in which a
phosphate group joins adjacent carbons through ester
linkages. A condensation re
action between adjacent
nucleotides results in a
phosphodiester bond between 3' and 5' carbons in
DNA and
RNA.

enzyme which cleaves
phosphodiester bonds that link adjacent
nucleotides in
DNA and/or
RNA. An
exonuclease progressively cleaves from the end of the
substrate molecule; an
endonuclease cleaves at internal sites within the
substrate molecule.
