My Mitoses Flip book.

1. Mitoses The reproduction of a cell By Rachel Nickason

2. Interphase

3. Interphase During this phase the cell is preparing for mitosis, The reproduction of a cell. Chromosomes are not yet visible, though the nucleolus very well could be.

4. Prophase

5. Prophase The chromosomes are now visible and they form an ‘X’ shape. The nucleolus disappears, and Spindle Fibres start to form.

6. Prometaphase

7. Prometaphase The Nuclear membrane dissolves The beginning of Prometaphase has started. Proteins attach to the centromeres making kinetochores. The chromosomes begin to move along the fully formed spindle fibres

8. Metaphase

9. Metaphase Spindle Fibres conduct the chromosomes along the middle of the cell nucleus. This group helps ensure that in the next phase (Anaphase) The new nucleus will get a copy of each chromosome. *The Line of chromosomes Is also known as the metaphase plate

10. Anaphase

11. Anaphase The ‘X’ shaped chromosomes separate into two and move to opposite ends of the cell.

12. Telophase

13. Telophase A nucleolus forms around the chromosomes that have divided to the ends of the cells. A new membrane forms around the daughter cell’s nuclei, the chromosomes disappear and are no longer visible. The Spindle Fibres Also disappear during this phase.

14. Cytokinesis

15. Cytokinesis Cytokinesis happens when a fibre ring made of protein, contracts around the center of the cell pushing it into two daughter cells, each having one nuclease. Source http://www.biology.arizona.edu/Cell_bio/tutorials/cell_cycle/cells3.html
