The reaction that joins a nucleotide to a growing polynucleotide chain requires nucleotide triphosphates as the monomer units, energy (which is provided by the hydrolysis of the triphosphates), a 3′ alcohol group on the growing chain to which the new nucleotide is added, and a 5′ phosphate group on the incoming nucleotide that forms a phosphodiester bond with the 3′ alcohol group.
