1. Mitosis Notes

2. Cell Division occurs in
a series of stages,
or phases

3. Interphase 1st Phase - Interphase Chromosomes are replicated (doubled)
Chromosomes appear as threadlike coils called chromatin
3 parts of Interphase – G1, S and G2

4. Prophase 2nd Phase - Prophase
Chromatin coils up and condenses into chromosomes
Nuclear membrane dissolves
Spindle starts to form

5. Metaphase 3rd Phase – Metaphase
Sister chromatids line up at the MIDDLE of the cell
Sister chromatids are attached to the spindle by the centromere

6. Anaphase 4th Phase – Sister chromatids split at the centromere
Sister chromatids move APART/AWAY from each other as the spindle fibers shorten

7. Telophase 5th Phase – Spindle dissolves Telophase
Nuclear membrane reforms around the TWO nuclei
Chromosomes turn back into chromatin

8. Cytokinesis
6th Phase –
Cytokinesis
CELL MEMBRANE pinches off in between two cells and splits cell into two new cells
Both cells have IDENTICAL DNA
