The 3′ - 5′ phosphodiester linkages inside a polynucleotide chain serve to join

Question

The 3′ - 5′ phosphodiester linkages inside a polynucleotide chain serve to join (A) one DNA strand with the other DNA strand (B) one nucleoside with another nucleoside (C) one nucleotide with another nucleotide (D) one nitrogenous base with pentose sugar.

Tardigrade Admin · Accepted Answer

A phosphodiester bond is formed between the phosphate group, which is connected to carbon 5′ of the sugar residue of one nucleotide, and the hydroxyl group attached to carbon 3′ of the sugar residue of the next nucleotide.
