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

When nucleoside is linked to phosphoric acid at 5.-position of sugar moiety, we get a nucleotide. Nucleotides are joined together, by phosphodiester linkage between 5. and 3. carbon atoms of the pentose sugar.
