1. Why are there many checkpoints in the cell cycle?

• To ensure that cells are made normally• If all checkpoints fail, tumors can result

Control of the Cell Cycle Internet Activity

1. G1- Makes the decision if the cell should divide, delay division, or enter resting stage.

G2- Check the success of DNA replication and begin mitosisM- Triggers the exit from mitosis and cytokinesis. Begins G1. 2. Cdk- carry the cell past the checkpoint and into mitosisCyclin- tells the cell when it is time to start/stop the cell cycleWhen the level of MPF is high enough the G2 phase ends and mitosis begins. It also destroys cyclin.

1. To replace dead or injured cells. Development of a fertilized egg.

2. 300 million3. Skin cells- very oftenLiver cells- sometimesBone marrow- continuouslyStomach lining- continuously

4. When a cell dies, it breaks up and leaves an empty space in the tissue5. CDKCyclin

7. Checkpoint 1- the end of G1Checkpoint 2- during S phaseCheckpoint 3- during M phase8. So that the daughter cells produced are exact copies of the mother cell9. Changes in the chromosomes (mutations)10. Cells may become cancer cells, which have altered chromosome

OBJECTIVE: We will learn to 1. Communicate our knowledge of

each phase of cellular division. 2. Explain the difference between

cell division of prokaryotic and eukaryotic cells.

Closure

1. What are the major events that occur during each of the stages in the life cycle of a cell such as a skin cell, i.e., Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis? Assume you are a court reporter that has to explain these stages to your readers with as little jargon as possible.

2. How does cell division differ in prokaryotes and eukaryotes? Clearly, these differences may be difficult for the prokaryotes in the jury to follow unless you show the similarities and differences.
