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.
A free 3'OH group is required for replication, but when the two chains separate no group of that nature exists. RNA primers are synthesized, and the free 3'OH of the primer is used to begin replication. The replication fork moves in one direction, but DNA replication only goes in the 5' to 3' direction.
