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.
Before DNA Replication (S Phase) - A chromosome. After DNA Replication - a duplicated chromosome, made up of 2 sister chromatids. The sister chromatids are pulled apart during mitosis (division of the nucleus), and partitioned into the 2 new daughter cells by cytokinesis (division of the cell). Result of mitosis: two daughter cells genetically identical to the parent cell.
