But remember our DNA polymerase can only read the parent strand in the three to five direction. So that means the DNA polymerase has to move in the opposite in the backward direction. So what actually happens the way we synthesize this strand, which is known as the Lagging strand is in the following manner. Our primase actually lays down many of these RNA primers. So we have one two RNA primers as shown and our DNA polymerase binds to each one of these primers and it creates our blue strands which are the dota strands in the opposite direction with respect to the movement of this DNA polymerase and this DNA helicase molecule. So the DNA polymerase is still synthesizing in the five to three fashion, but in this case, it must move in the opposite direction with respect to this DNA polymerase.
