STOP-MOTION ANIMATION

Early Prophase

Late Prophase

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
