 Mitosis is the process by which a cell separates the chromosomes in its cell nucleus, into two identical sets in two daughter nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two daughter cells containing roughly equal shares of these cellular components.

Tornados Storm America

Three powerful tornadoes have ripped through the American state of Virginia, injuring more than 200 people and destroying loads of buildings.

Thousands of homes were affected by power cuts as the storms tore through the eastern state on Monday afternoon.

The southern city of Suffolk was among the hardest hit. Cars were flipped over, roofs blown off houses and trees and power lines brought down.

Officials have declared a state of emergency in the worst-affected areas.

 A Tornado forms when warm winds meet cooler winds, as the two winds move around each other a spiral of spinning air forms, this is know as a vortex . The vortex can spin at up to 300 mph. A wind that strong can destroy most things in its path. Objects, animals and even people have been picked up and hurled many miles away!
