Odile struck Sunday evening near Cabo San Lucas as a Category 3 hurricane, with winds at 125 mph, the National Hurricane Center in Miami reported. It tied as the strongest hurricane on record to make landfall in the Baja Peninsula, matching Hurricane Olivia in 1967, Weather Underground meteorologist Jeff Masters said.
Here's what happens: 1  At first the cells have the same number of chromosomes as mitosis. DNA replication occurs, giving a total of 46 chromosomes (or 23 chromosome pairs) and 92 chromatids (or 46 chromatid pairs). 2  Meiosis I: In meiosis I, the homologous chromosomes separate.
DNA replication, the process by which genetic information is duplicated, occurs in order to ensure that each cell in an organism has a complete and correct copy of the organism's genome, or library of genetic data.NA replication occurs in two different forms of cellular division. The first is mitosis, which serves all of the normal needs of growth, maintenance, and repair within an organism. In mitosis, a single cell divides into two, each with its own set of genetic information.
