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 WebThe primase generates short strands of RNA that bind to the single-stranded DNA to initiate DNA synthesis by the DNA polymerase. This enzyme can work only in the 5' to 3' direction, so it...

WebSep 15, 2024 · DNA polymerase works by sliding along the single strand template of DNA reading its nucleotide bases as it goes along and inserting new complementary nucleotides into the primer so as to make a sequence complementary to the template.

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 Web4.
