Now let's take a look at the following bottom parent DNA molecule that runs in the three to five direction. Now our DNA polymerase can only read the parent strand from the three to the five direction and this means that it can only synthesize the new strand in the five to three direction. So for this bottom strand that basically means that when the primates creates the RNA primer the DNA polymerase can basically synthesize our new daughter strand in the same direction as the movement of the fork as the movement of the DNA helicase molecule. So if this DNA molecule, the DNA helicase molecule moves in the forward direction that means that this DNA polymerase also moves in the forward direction because it creates this new strand from the five to the three direction. However, let's take a look at this upper strand here. So for the case of this upper parent strand if our DNA polymerase reads it this way in the same forward direction then it reads our strand in the five to three direction.
