1. Cell Cycle Graphic Organizer
For this Activity You will Need:
Blue Colored Pencil
Red Colored Pencil
Green Colored Pencil
Lead Pencil

2. Cell Cycle – Big Picture
DNA copied
DNA is equally
divided
Cell splits apart

3. Goal of Cell Cycle Goal:
To make 2 identical cells with the SAME number of DNA molecules as the original cell
Let’s follow how the DNA moves in this process. You will see
that the DNA is moved very carefully to make sure that each cell
gets the SAME amount.

4. 1. Interphase 1. Interphase Cell Grows DNA Doubles Started with:
2 red chromosomes
2 blue chromosomes

5. 2. Mitosis A. Prophase (P=Prepare)
Centrioles
A. Prophase (P=Prepare)
Chromatin coils into duplicated chromosomes
Nucleus disappears
Spindle fibers shoot out from centrioles

6. 2. Mitosis B. Metaphase (M=Middle)
Spindle Fibers
B. Metaphase (M=Middle)
Spindle fibers pull duplicated chromosomes to the middle of the cell
Duplicated Chromosomes

7. 2. Mitosis C. Anaphase (A=Apart)
Duplicated chromosomes split at centromere
Fibers pull chromosomes to opposite ends of cell

8. 2. Mitosis D. Telophase (T=Tear) Chromosomes uncoil into chromatin
Nucleus reappears
Spindle fibers disappear

9. 3. Cytokinesis 3. Cytokinesis Cytoplasm & organelles divide
Cell splits into two new cells

10. Cell Cycle – Revisit the Big Picture
THINK! – What happens in each stage? 1. 2. 3.
DNA is copied
DNA is
equally
divided
Cell splits apart
into 2 separate cells
