What are the 5 stages of mitosis | Interphase, Prophase, Metaphase, Anaphase, Telophase |
What happens in Interphase | A copy is made of all of the chromosomes in the nucleus |
Describe Prophase | Chromosomes shorten and thicken becoming visible. Nuclear membrane disappears. |
Describe Metaphase | Chromosomes line up at the equator of the cell. Spindle fibres appear |
Describe Anaphase | Spindle fibres pull chromosomes to the poles of the cell |
Describe Telophase | Nuclear membranes appear round chromosomes at the poles of the cells Cytoplasm begins to divide to form 2 cells |
