- Which<br/>is correct about DNA polymerase and RNA polymerase:() A: RNA<br/>polymerases use nucleoside diphosphate instead of nucleoside<br/>triphosphate for synthesis of polynucleotide chains B: RNA<br/>polymerases need primer and add nucleotides in the 5 'end of the<br/>polynucleotide chain C: DNA<br/>polymerase can add nucleotides in both ends of the polynucleotide<br/>chain D: All<br/>of the RNA polymerases and DNA polymerases can only add nucleotides<br/>in the 3’ end of the polynucleotide chain
