Phases of Mitosis

Question	Answer
Prophase	The nuclear membrane starts to break down. The centrioles start to move to the poles of the cell and make spindle fibres. Chromosomes super coil and condense and becomes visible, appears as 2 identical sister chromatids joined at the centromere.
Metaphase	Centrioles complete the production of spindle fibres. Chromosomes are attached to the spindle fibres by thier centromere. Chromosomes align down the equator of the cell.
Anaphase	Spindle fibres contract. Centromeres splits. Identical chromatids are pulled to opposite poles, making a 'v' shape.
Telophase	nuclear membrane starts to form around each set of chromosomes. the chromatids becomes invisible.
Cytokinesis	the surface membrane pinches together and 2 daughter cells form.
