Which moieties of nucleosides are involved in the formation of phosphodiester linkage present in dinucleotides? What does the word diester in the name of linkage indicate? Which acid is involved in the formation of this linkage?

Explanation

In the formation of dinucleotides, the 3' `-OH` group of one nucleotide unit `5'-OH` group of the other nueleotide molecule are involved to form the phosphodiester linkage.The acid involved in this linkage is phosphoric acid and the word diester in this linkage indications that two `OH` groups of phosphoric acid are involved in the formation of ester linkages.
