So therefore the polymerase forms the lagging strand in a piece wise fashion. So piece by piece in a discontinuous manner and each one of these pieces is known as the Okasagi fragments. Now, this process is important because it basically ensures two important things. Firstly, as our helicase moves this way we see that the DNA polymerase is able to actually form the leading strand and our lagging strand at about the same exact time. And this type of process also ensures that the DNA polymerase creates both of these strands in the five to three direction. So, going this way, we synthesize in a five to three fashion.
