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 primer acts as the starting point for DNA synthesis. 2  DNA polymerase binds to the leading strand and then âwalksâ along it, adding new complementary nucleotide bases (A, C, G and T) to the strand of DNA in the 5â to 3â direction. 3  This sort of replication is called continuous.
