Cell Division = Mitosis + Cytokinesis

* Remember the chromosomes have already duplicated prior to Mitosis

Prophase

- chromosomes appear (condensed)

- centrioles begin to move to opposite ends of the cell

- nuclear membrane begins to disappear

- spindle fibers form
Lesson 1 Cell Division + Mitosis.notebook April 25, 2020

Metaphase

- Chromosome line up across equator (center) of cell

- spindle fiber attaches at the centromere

Anaphase

- sister chromatids separate

- attached to a spindle fiber and begin to be pulled toward centriole

Telophase

- chromosomes de condense

- nuclear membrane forms around each group of chromatin

Cytokinesis occurs next

- cell pinches off into 2 new daughter cells

- cytokinesis is part of the M phase but not part of Mitosis

* The cells are now ready to enter interphase
