A
Interphase:
centrioles begin replicating
DNA is replicated
Final preparations for mitosis are completed and centroles finish replicating

A
Early Prophase
- Chromatin Condenses forming barlike chromosomes
- Nucleoli disappears
- Centrosomes separate
- Microtubules lengthen and begin forming the mitotic spindle
- Asters extend from the centrosome matrix

A
Late Prophase
- Nuclear envelope breaks
- Microtubules attach to kinetechores as the chromasomes centromere.
- Kinetechore microtubules pull on each chromosome from both poles pulling chromosomes to the center of the cell

A
Metaphase
- Centrosomes are at the opposite sides of the cell
- Chromosomes cluster at the midline centromeres precisely aligned at the equator: metaphase plate
- Enzymes separate the chromatids

A
Anaphase
- Kinetechore mictrobules pull chromosomes to opposite poles
- Moving chromosomes look v-shaped

Q

A
Telophase
- begins when chromosomal movement stops
- chromosomes begin to uncoil into chromatin
- nuclear envelope begins to form and nucleoli reappear
- spindle breaks down
7
Q
Cytokinesis
A
A contractile ring of actin forms the cleavage furrow and pinches the cell apart.
Begins in late anaphase and goes through telophase.
