Purple Mice Are Tasty |

|
What happens at the Prophase stage? |
-Chromosomes condense, getting shorter and fatter. -Tiny bundles of centrioles start to move to opposite ends of the cell (forms spindle fibres) -Nuclear envelope starts to break down |
|
|
What happens at the Metaphase stage? |
-Chromosomes line up along the spindle equator -Become attached to the spindle by their centromere -At metaphase checkpoint, cell checks that all the chromosomes are attached to the spindle. |
|
|
What happens at the Anaphase stage? |
-Centromeres divide, separating the pair of sister chromatids -Spindles shorten -Chromatids are pulled to opposite ends of the cell (centromere first) |
|
|
What happens at the Telophase stage? |
-Chromatids uncoil and become long and thin again -Called chromosomes again -Nuclear envelope forms around each group of chromosomes -Now two nuclei |
|
|
What is Cytokineses? |
-Cytoplasm divides -Animal cells, a Cleavage Furrow forms to divide the membrane (protein is actin) -Now two daughter cells (genetically identical to each other and original) |
|
|
What is the significance of Mitosis? |
-Growth of the organism -Repair of tissue -Replacement of old cells -Asexual reproduction |
