Now once the proteins, once the group of proteins binds to the DNA molecule at the point of origin replication proceeds on both strands but it takes place in opposite direction. So to see what we mean let's take a look at the following diagram. So let's suppose we have the original DNA molecule shown. We have one of the strands shown in blue and the second parent strand is shown with this brown color. Now, what basically happens is our groups of proteins including our helicase, binds to the point of origin. Let's suppose in this location and one of the newly synthesized single stranded DNA molecules is synthesized in this direction and the other DNA molecule, the other single stranded DNA molecule, the daughter strand is synthesized in the opposite direction.
