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 is the process by which DNA makes a copy of itself during cell division.1  The first step in DNA replication is to âunzipâ the double helix structure of the DNA molecule. The separation of the two single strands of DNA creates a âYâ shape called a replication âforkâ. 2  The two separated strands will act as templates for making the new strands of DNA. 3  One of the strands is oriented in the 3â to 5â direction (towards the replication fork), this is the leading strand.
