Homework: Homework Packet 7 Due Friday

2. Cancerous cells vs. normal cells
Observations?
Questions?

3. Cancerous Cells
By definition, cancerous cells are cells that divide uncontrollably
Meaning, they constantly go through mitosis with no regulation or reason to

4. Group Brainstorm
After viewing the video, brainstorm some ideas for how we could prevent cancerous cells from dividing uncontrollably and stop the cancerous cell from spreading

5. Cell Cycle Checkpoints
During the life of the cell, there are checkpoints that:
Make sure only healthy cells divide
Make sure cell division only happens when it is needed
Remember that interphase is our longest phase
1. G1 phase
2. S phase
3. G2 phase

6. Create a paper plate model using the diagrams provided
Required items:
4 Phases of Cell Cycle Labeled
Description of what occurs in each phase
Description of 3 checkpoints in their correct phase
Label which phases are mitosis and which are interphase

7. Checkpoints
G1 Checkpoint: Is the cell the correct size? Does it have enough nutrients?
G2 Checkpoint: Did the DNA replicate properly, without any errors?
Metaphase Checkpoint: Are all the chromosomes aligned properly in the middle of the cell?
