Lesson 3.5.2

Lesson 2—The Cell Cycle and Cancer

 

Get Focused

 

Ponce de Leon, a Spanish explorer, spent years looking for the fountain of youth in a part of North America now called Florida. Of course he never found it, but imagine if there was one, and you could drink from it! Life would be yours for hundreds of years. No wrinkles until you were at least 500 years old! Alas, what is it that makes human cells last only a little more than one century at best? Why do cells age? Is there a secret to keeping body cells vigorous and young which has not yet been discovered?

 

In this lesson you will learn to identify the phases of the cell cycle. You will learn how a normal cell regulates this cycle, and how some cells can exit the cycle or may even ignore these clues.

 

In this lesson the following focusing questions will be examined:

 

  • What are the phases of the cell cycle?
  • Do all cells have the same ability to reproduce and does this change with age?

 

This lesson will take approximately 80 minutes to complete.
