1. Cell cycle/mitosis
Chapter 6

2. Why do cells divide? What does this mean?

3. Cell division:
The big picture

4. DNA replication-the big picture (many steps, many enzymes)

5. DNA replication

6. Cell division in prokaryotes
Called binary fission

7. The eukaryotic cell cycle

8. Interphase
In the nucleus,

9. Sister chromatids are

10. Mitotic phase division of nucleus prophase metaphase anaphase
telophase
cytokinesis: division of cytoplasm
division of nucleus

11. Prophase

12. Metaphase

13. Anaphase

14. Telophase & cytokinesis

15. Cytokinesis in animal cells

16. Cytokinesis in plant cells

17. You have to know the sequence in order!

18. Let’s review so far. . . How many parent cells?
How many daughter cells?
How many times did the DNA replicate before division?
How many mitotic divisions are there in each cycle?
How many chromosomes in daughter cells?
How are the daughter cells related to each other? Why?
How are the daughter cells related to the parent cell?
What are sister chromatids? When are they made?

19. Programmed cell death
Called apoptosis

20. Then what happens?
