1. The Cell Cycle

2. What is the cell cycle?
The stages are cell goes through to divide into 2 identical cells.

3. Two Parts of the Cell Cycle
Interphase – “resting” phase
Cell carries out “normal” day to day activities
Mitosis – Division of the nucleus

4. Who is involved? Parent Cell – The starting cell
Daughter Cell – The resulting cells (usually 2)

5. Interphase is made up of three stages:
G1 – Gap 1 – Makes more organelles and cytoplasm
S phase – Synthesis – More DNA is made; DNA is replicated
G2 – Gap 2 – Cell checks for errors and gets bigger.

6. Form of DNA during Interphase
Chromatin – Long and stringy

7. Mitosis Notes

8. What is Mitosis?
Division of the nucleus

9. Form of DNA during Mitosis
DNA is in the form of chromosomes

10. Stages of Mitosis in Order
Prophase
Metaphase
Anaphase
Telophase

11. Prophase - Preparing Chromatin  Chromosome
Nuclear membrane disappears
Mitotic Spindle forms

12. Metaphase - Middle
Chromosomes line up in the middle

13. Anaphase – Apart
Chromosomes get pulled apart to opposite ends of the cell

14. Telophase - Two Two new nuclei form Chromosome  Chromatin
Cleavage furrow forms

15. Followed by …
Cytokinesis
division of the cytoplasm

16. What is produced?
2 cells that are identical to each other
