1. MITOSIS! Review Mitosis has 4 stages: – Prophase – Metaphase – Anaphase – Telophase Mitosis is the process by which the nucleus of a cell divides into TWO IDENTICAL nuclei

2. Why is it important that the nucleus divides into IDENTICAL nuclei? Remember: the nucleus contains the genetic information – Genetic information = GENES! (section of DNA) – Genes are located on chromosomes, which are long linear strands of DNA So the cell has all the information it needs to create NEW cells!

3. On the back of your mitosis worksheet please write these headings: PROPHASE METAPHASE ANAPHASE TELOPHASE

4. PROPHASE Chromosomes have made a copy (replicated) and are now visible

5. METAPHASE Replicated chromosomes line up in the center of the cell

6. ANAPHASE The identical chromosomes separate and begin to move toward opposite ends of the cell

7. TELOPHASE Chromosomes are harder to see as the nucleus membrane forms around them Now what happens?

8. Cytokinesis! After the nucleus has divided, it is followed by the cytoplasm dividing
