WebRNA primers are used by living organisms in the initiation of synthesizing a strand of DNA.A class of enzymes called primases add a complementary RNA primer to the reading template de novo on both the leading and lagging strands.Starting from the free 3’-OH of the primer, known as the primer terminus, a DNA polymerase can extend a newly synthesized strand. 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 binds to a sequence of DNA called the promoter, found near the beginning of a gene.
