1. AGENDA – 11/5/15 Take out journal! DNA and Cell Cycle Review Game Finish Exam Study Guide Homework: TEST TOMORROW! Exam Study Guide due tomorrow! JOURNALS DUE TOMORROW!

2. Cell Cycle Review Game ROUND 1 – 5 POINTS EACH ROUND 2 – 10 POINTS EACH ROUND 3 - 15 POINTS EACH

3. 1. What is the final step of the cell cycle?

4. Cytokinesis

5. 2. List three ways that DNA and RNA differ.

6. -DNA is double stranded, RNA is single stranded -The sugars are different -RNA has uracil instead of thymine -DNA can not leave the nucleus

7. 3. A cell contains 24 chromosomes. It goes through mitosis/ cell cycle. How many chromosomes does each of the new daughter cells contain?

8. 24 3. A cell contains 24 chromosomes. It goes through mitosis/ cell cycle. How many chromosomes does each of the new daughter cells contain?

9. 4. What makes cancer cell division different from your normal cell’s division cycles?

10. Skips G0, and continuously goes through the cell cycle, and divides over and over

11. 5. What is the name of the structure below?

12. Nucleotide

13. ROUND 2

14. 1. Below are the pictures of the four phases of mitosis. Name them and put them in order of occurrence. A. B. C. D.

15. 1. Below are the pictures of the four phases of mitosis. Name them and put them in order of occurrence. A. anaphaseB. metaphaseC. telophaseD. prophase

16. 2. What is the name of the enzyme in the picture below AND what does it do?

17. Helicase- breaks the hydrogen bonds, unzips DNA

18. 3. During what phase of nuclear division does chromatin coil up into chromosomes?

19. Prophase

20. 4. During what stage of the cell cycle does the below process occur?

21. INTERPHASE (specifically “S”)

22. Section 3 Check 5. All humans should have 46 chromosomes. So if you have 46 with A, T, C, and G….and the person next to you has 46 with A, T, C, and G….what makes you different from each other?

23. Section 3 Check 5. All humans should have 46 chromosomes. So if you have 46 with A, T, C, and G….and the person next to you has 46 with A, T, C, and G….what makes you different from each other? The Sequence of Bases All organisms have DNA and have ATCG in their DNA….amts and sequences make us different.

24. Based on the information, which percentage would best represent a predicted amount of Cytosine in the Herring DNA? A. 25 B. 28 C. 22 D. 44

25. Based on the information, which percentage would best represent a predicted amount of Cytosine in the Herring DNA? A. 25 B. 28 C. 22 D. 44

26. ROUND 3

27. 1. What specific phase is occurring at the place indicated?

28. Metaphase

29. 2. Give two reasons why cells need to divide to make new cells.

30. Repair, Replace Dead, Growth

31. 3. What three main things occur during Interphase?

32. Growth, Organelle duplication, DNA replication

33. 4. What phase comes after the phase below?

34. Telophase

35. 5. What is the difference between the DNA replication that occurs in Interphase and what happens to the chromosomes during anaphase?

36. DNA replication, a copy of the dna is being made….Anaphase the replicated pieces are being split apart
