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.
The single molecule of DNA that is the E. coli genome contains 4.7 x 10 6 nucleotide pairs. DNA replication begins at a single, fixed location in this molecule, the replication origin, proceeds at about 1000 nucleotides per second, and thus is done in no more than 40 minutes.eplication begins at some replication origins earlier in S phase than at others, but the process is completed for all by the end of S phase. As replication nears completion, bubbles of newly replicated DNA meet and fuse, finally forming two new molecules.
