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.
