So first we have the primates that lays down the RNA primer. So let's suppose we have our RNA primer as shown and then what happens? Our DNA polymerase basically continuously forms our nucleotide piece by piece. So we form the following continuous strand and notice the formation actually takes place in the same exact direction as the movement of our helicase. So the helicase, this enzyme moves to the left along our x axis and the replication also takes place in the same direction towards the left, along our x axis. So because this is the three end, this end of the new daughter new strand is our five end and this is the three end.
