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 begins at a specific spot on the DNA molecule called the origin of replication. At the origin, enzymes unwind the double helix making it accessible for replication. Each strand of the helix then separates from the other, exposing the now unpaired bases to serve as templates for new strands.
