2. Q&A Review Unit 3 Part 2 Cell Cycle and Mitosis

3. Stages of Cell Division What happens in anaphase? What happens in prophase?

4. Mitosis: Dividing DNA & cells Stage 1: cell copies DNA nucleus cell DNA Copy DNA! (interphase)

5. Mitosis: Dividing DNA & cells Stage 2: DNA winds into chromosomes –DNA is wound up into chromosomes to keep it organized nucleus cell duplicated chromosomes Wind up! (prophase)

6. Mitosis: Dividing DNA & cells Stage 3: Chromosomes line up –chromosomes line up in middle –attached to protein “cables” that will help them move duplicated chromosomes lined up in middle of cell Line up! (metaphase)

7. Mitosis: Dividing DNA & cells Stage 4: Chromosomes separate –chromosomes split, separating pairs –start moving to opposite ends chromosomes split & move to opposite ends Separate! (anaphase)

8. Mitosis: Dividing DNA & cells Stage 5: Cell starts to divide –cells start to divide –nucleus forms again Divide! (telophase)

9. Mitosis: Dividing DNA & cells Stage 6: DNA unwinds again –cells separate –now they can do their every day jobs Bye Bye! (cytokinesis)

10. New “daughter” cells Get 2 exact copies of original cells –same DNA –“clones”

11. Cell division in Animals

16. Centrosomes vs. centrioles vs. chromatids vs. chromatin vs. chromosomes What happens when the chromatids don’t line up correctly? Do chromosomes form during DNA synthesis?

17. Cell cycle

18. What is cytokinesis?

19. How are the stages of mitosis related?

20. What do the other organelles do (besides nucleus) when going through mitosis?

21. How long does the cell cycle take for different organisms?

22. What triggers cell division?

23. Cell division in plants vs. animal cells

24. Cell cycle vs. mitosis

25. Binary fission vs. mitosis

26. What are histones?

27. CDK vs. cyclin?

28. Why do you give a dehydrated patient saline solution? Why not plain water?

29. Why does it take nutrients longer to enter a bigger cell?

30. Does organelle duplication occur in G 1 ? Book says yes; POGIL says no…?
