DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
DNA replication begins at the Origin of Replication (ORI) 1  Each DNA molecule has specific points on the double helix where enzymes need to attach to begin replication. 2  The enzymes that attach to the ORI are topoisomerase and helicase.
