Cabo San Lucas, Mexico â Residents and tourists hunkered down in shelters and hotel conference rooms overnight as a powerful and sprawling Hurricane Odile made landfall on the southern Baja California peninsula.
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 in eukaryotes occurs only in the S phase of the cell cycle. However, pre-initiation occurs in the G1 phase. Thus, the separation of pre-initiation and activation ensures that the origin can only fire once per cell cycle.
