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.
Before fission can occur, the cell must replicate its chromosome, which is circular. This process starts when a replication bubble opens in the DNA of the chromosome. There is normally a single origin of replication in prokaryotes, not multiple ones as is the case in eukaryotes.
