Hurricane Odile was the most powerful storm to hit Cabo San Lucas on the Baja California peninsula in Mexico. A Category 3 hurricane when it made landfall, Odile had winds of 125 mph. But the hurricane is losing strength as it moves north.
The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period.
Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a personâs body has the same DNA.ach strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
