1. First Foldable: The Cell Cycle
Page 41 in your notebook

2. Flap 1: Gap 1 (G1) - First stage of the cell cycle
- Cell carries out normal functions
- Cell increases in size, organelles increase in numbers

3. Flap 2: Synthesis (s) - Second stage of the cell cycle
- The cell makes an identical copy of the DNA in the nucleus

4. Flap 3: Gap 2 (G2) - Third stage of the cell cycle
- Additional growth occurs
- Cell goes through a critical checkpoint to make sure everything is in order

5. Flap 4: Mitosis - Final stage of cell cycle
- Division of the cell to create two identical daughter cells
- Ends with cytokinesis, the division of the cell cytoplasm

6. Second Foldable: Mitosis

7. Flap 1: Prophase - DNA and proteins condense into chromosomes
- The nucleus begins to break down
- Centrioles move to opposite poles
- Spindle fibers form

8. Flap 2: Metaphase - Spindle fibers attach to each chromosome
- Chromosomes line up along the middle of the cell

9. Flap 3: Anaphase
- Chromatids (halves of the chromosomes) separate and move to opposite side of the cell

10. Flap 4: Telophase - Two new nuclear membranes form
- Chromosomes begin to uncoil
- Spindle fibers fall apart
- Cytokinesis occurs, dividing the cytoplasm between the two daughter cells
