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 has to replicate before mitosis to keep the number of chromosomes and DNA in the cell consistent. Mitosis is the process of reproducing cells by splitting one cell in half â¦ to make two.If the DNA didn't replicate, the two daughter cells wouldn't be able to have a complete strand.DNA replicates by dividing in half, then creating a mirror image of itself.NA replication mus occur before mitosis starts. Mitosis is another  word for cell division and so there must be two copies of DNA for  each cell at the end stage.
