<span>These three different subsets of bacteria although all from the same family have very different qualities. They are related by their common biological mechanisms though.</span>
<span>The action of Helicase is to create replication forks and replication bubbles. Helicase is the first step in the DNA replication process. Helicase is an enzyme that breaks the hydrogen bond between the parental DNA to free the DNA double helix. The area where it unwinds is called as replication fork.</span>
