WebDNA Polymerase reads from the 3’ to 5’ in one strand. In order to make the other strand it adds nucleotides in the 3’ end. For example, if the top strand is from 5’ to 3’, the polymerase simply adds nucleotides to the 3’ end since the strands are anti parallel. [deleted] • 3 yr. ago DearFutureDoctor • 3 yr. ago

WebRNA polymerase then starts to synthesize the initial DNA-RNA heteroduplex, with ribonucleotides base-paired to the template DNA strand according to Watson-Crick base-pairing interactions. As noted above, RNA polymerase … Web"RNA polymerases are enzymes that transcribe DNA into RNA. Using a DNA template, RNA polymerase builds a new RNA molecule through base pairing. For instance, if there is a G in the DNA template, RNA polymerase will add a C to the new, growing RNA strand. RNA polymerase always builds a new RNA strand in the 5’ to 3’ direction." Translation
