Early Prophase

Late Prophase *Ignore the pink until Telophase

Metaphase

Anaphase

Telophase

Early Protophase  First Stage of mitosis  Replicated chromosomes coil up into X- shaped chromosomes  Nucleolus disappears and nuclear membrane begins to break down  Spindle Fibres begin to form  Centrioles begin to move apart (Animal Cell)

Late Prophase  Centrioles complete forming  Spindle fibres and chromosomes attach at the centromeres  Nuclear membrane disappears

Metaphase  Spindle fibres tug at each other forcing the X-shaped chromosomes into a single line across the center

Anaphase  Spindle fibres contract and shorten  Centromere gets pulled apart  Sister chromatids are pulled to each poles of the cell  Sister chromatids are now considered chromosomes

Telophase  Final Stage of mitosis  One complete set of chromosomes are at each pole  Spindle Fibres disappear  Nucleolus and Nuclear membrane forms once again  Cell is ready to divide
