1. Warm up: 1. What are the 3 parts to cell theory? 2. How are new cells "born"?

2. Cell Division Chapter 2; Section 1

3. All cells can divide Parent cell: original cell Daughter cells: 2 new cells after division

4. DNA must divide for a cell to divide. What is DNA?

5. With your partner, take the "Tour of the Basics" Its link is on the class website, Cell and Heredity Chapter 2. Complete the webquest.

6. DNA: DeoxyriboNucleicAcid The genetic material for your cells Makes you who you are!

7. DNA Structure: 2 Long Strands attached at middle Nucleotides -Phosphate -Sugar (deoxyribose) -Base (adenine---thymine, guanine-----cytosine)

8. Put together the DNA model from your pages. The bases in the center are like puzzle pieces! Answer the questions on the back.

9. Genes are pieces of DNA Provide instructions for cell functions or traits Make proteins

10. Chromosomes are structures made of DNA wrapped around proteins Prokaryote Eukaryote

11. Humans have 23 pair of chromosomes The last pair is XX in females and XY in males

12. Typical Chromosome:

13. Warm Up: 1. Where is protein actually made? 2. Where are the instructions for making proteins stored? 3. What is the difference between chromosomes and genes?

14. Mitosis: Nuclear division DNA replicates and then divides into 2 "new" cells

15. Eukaryotic Cell Division: Mitosis is nuclear division Read p 42-45 in hard cover text

16. Extraction of DNA!!!!!

17. Warm up 1. What is mitosis? 2. What are some of the steps that happen in mitosis?

18. Please take the You Be the Chemist test DO NOT write on the test packet Cover your answers until all are finished

19. YBTC Key 1.D 2.D 3.B 4.A 5.C 6.B 7.B 8.C 9.A 10.A 11.B 12.A 13.A 14.D 15.C 16.B 17.B 18.C 19.C 20.B 21.C 22.C 23.B 24.B 25.C

20. Eukaryotic Cell Division: Mitosis is nuclear division

21. Watch the video and complete the stages web

22. nuclear division Prophase Metaphase Anaphase Telophase Chromosomes condense & nuclear membrane disappears Chromosomes move to middle Chromosomes move apart Cells pinch apart and all organelles divide create new cells

23. Now...use your web to complete the mitosis wheel

24. Chromosomes condense & nuclear membrane disappears Chromosomes move to middle Chromosomes move apart Cells pinch apart and all organelles divide Cells grow and DNA replicates

25. Cells have a cell cycle It includes all the stages a cell goes through Mitosis (cell division) is only 1 small part Mitosis creates new, identical cells

26. DNA Replication MUST occur for cells to divide

27. Interphase C ells grow DNA is copied (replicated)

28. Prophase C hromosomes condense Nuclear membrane disappears

29. Metaphase C hromosomes line up at the Middle

30. Anaphase C hromosomes move Apart

31. Telophase N ew nuclei are formed Cell pinches in the middle Daughter cells

33. Prokaryote cell division:

34. Why is cell division more complicated in Eukaryotes than it is in prokaryotes?
