Cell Cycle Project: Modeling The Cell Cycle
There are three steps to the cell cycle: Interphase, Mitosis, and Cytokinesis. During
Interphase, the cell prepares to reproduce itself. During mitosis, a cell’s nucleus divides into two
new nuclei with identical genetic material. In Cytokinesis, the cell divides the cytoplasm and
creates 2 new daughter cells. In this project, you will create a model to represent what happens
to the DNA of the cell in each step of the cell cycle.
Procedure:
1. Construct a model of a cell that has four chromosomes using chenille sticks, straws, or
colored thread to represent the chromosomes.
2. Position the chromosomes in the cell where they would be during each step. Use the
figure of the cell cycle in your book as a guide.
3. You may design your model any way you like, but be sure it represents each step of the
cell cycle.
4. When you have completed your model, answer the following questions IN COMPLETE
SENTENCES. Do this in a Word document.
a. Why is it important that the cell makes an identical copy of the DNA during
interphase?
b. Why does the nuclear membrane have to dissolve during prophase? Why does it
have to reappear in telophase?
c. How does the cell cycle help you and your body?
5. EXTRA: Create a model that represents how cytokinesis happens in a plant cell. Add
this question to #4.
…..d. Why is cytokinesis different for plant cells?
6. Fill in the Student Assessment column of the rubric on the back of this sheet. Use this
grading scale:
