Mitosis

1. happens Inside a cell in the nucleus 2. The Chromosomes duplicate 'unzip' while still attachted together at the //centromere//. This forms what is called sister chromotids. 3.Around this time the nucleus 'dissolves' (im not sure about this, the text book doesn't help). The chromotids all gather into a stright line at the centre of the cell also known as //Equator// (also called Centromere but i don't know thats what the text book says). 4.Spindle fibres that are attached to the //centromere (Note: the picture is wrong -.- sorry. the fibres are in the centre of the chromotids.)// 5.Spindle fibers then starts to shorten and then the chromotids split apart towards //poles// which are at the sides of the cell (its like the earth and the north and south poles and the equator). 6. The spindle fibres disappear and the nucleus or //nuclear membrane// forms around each group of chromosomes (so confusing! appearing and disappearing like magic -.-'') and the cell membrane pinches in( just like in binary fission), and closes to form two separate cells. 7. These cells are identicle genetically to the original cell.
