Now, the point at which our helicase is actually found at and the point where our unwinding is taking place is known as the fork of replication. So where the location where the helicase actually binds to is known as the origin. But as it moves, this location is known as the fork of replication. So the direction of the movement of the fork of replication is the same as the direction of the movement of our helicase enzyme. So as the helicase moves this way, the fork of replication also moves along with it. Now, as our doublestranded DNA molecule unwinds, it causes the DNA to super coil.
