3. Mitosis/Meiosis Jeopardy Mitotic Phases! Terms, terms Random Q $100 Q $200 Q $300 Q $400 Q $500 Q $100 Q $200 Q $300 Q $400 Q $500 Final Jeopardy DNA/ genes Meiosis Phases!

4. $100 Question from Mitotic Phases You are looking at a cell under a microscope, the chromosomes are visible but still in a central location. What phase is this and why?

5. $100 Answer What is prophase, because the chromosomes are visible, but not arranged in any specific way, still possibly in the nuclear envelope that is breaking down.

6. $200 Question from Mitotic Phases Name 2 things that occur during telophase.

7. $200 Answer What are: cleavage furrow forms, nuclear envelope begins to reappear, spindle beings to break down

8. $300 Question from Mitotic Phases During Anaphase there are 60 chromosomes in the cell, how many would be in each new daughter cell after cytokinesis?

9. $300 Answer What are- 30 chromosomes in each daughter cell.

10. $400 Question from Mitotic Phases Describe the parts of interphase and what occurs during each part.

11. $400 Answer What are- G1 (growth and normal cell behavior, S (DNA replication), & G2 (growth, preparation for mitosis, creating extra organelles)

12. $500 Question from Mitotic Phases During which phases are there homologous chromosomes in Mitosis?

13. $500 Answer What is: prophase & metaphase. Homologous chromosomes come together during prophase, line up during metaphase and are then pulled apart.

14. $100 Question from DNA/genes Define “chromosome.”

15. $100 Answer What is- a tightly packaged DNA molecule. DNA is wrapped around proteins and highly organized. Chromosomes are visible under a light microscope.

16. $200 Question from DNA/genes Come up to the board and draw/ label a chromosomes (with 2 things).

17. $200 Answer Like this drawing:

18. $300 Question from DNA/genes Describe one gene and two alleles of that gene.

19. $300 Answer Answers will vary. Example: hair texture; alleles would be straight, curly, wavy, etc.

20. $400 Question from DNA/genes What is an example of a genotype? (think back to the Reebop marshmallow lab)

21. $400 Answer Answers will vary. Example, Aa (2 antenna), ll (4 blue legs), tt (curly tail), etc.

22. $500 Question from DNA/genes What is the difference between the following: chromatin, chromatid, chromosome, tetrad

23. $500 Answer What is: chromatin is loose DNA that is not packaged around protein, in interphase; chromatid is half of a packaged chromosome (same genes coded for); chromosome is tightly packaged DNA around protein, could be replicated or unreplicated; tetrad is two homologous chromosomes attached during Meiosis I

24. $100 Question from Meiosis Phases What are 2 differences between Mitosis & Meiosis?

25. $100 Answer from Meiosis phases What are: mitosis involves one cell division while meiosis involves two; mitosis is with somatic cells (diploid) while meiosis creates sex cells (haploid), etc.

26. $200 Question from Meiosis Phases Describe what occurs during Anaphase I.

27. $200 Answer from Meiosis Phases During anaphase I, tetrads are pulled apart to homologous chromosomes that move towards opposite sides of the cell as the cell itself elongates.

28. $300 Question from Meiosis Phases What is the difference between Meiosis I and Meiosis II.

29. $300 Answer from Meiosis Phases What are: In meiosis I, tetrads form and are pulled apart into homologous chromosomes, each cell created is diploid. In meiosis II, homologous chromosomes pull apart into individual chromosomes creating four haploid cells.

30. $400 Question from Meiosis phases Differentiate between meiosis in men and women. Name at least 3 differences.

31. $400 Answer from Meiosis Phases What is- in men the process is called spermatogenesis, it creates 4 sperm cells of equal size. In women it is called Oogenesis, creating 1 egg cell and 3 polar bodies, due to an unequal division of the cytoplasm.

32. $500 Question from Meiosis Phases What occurs during what part of Meiosis that partially explains why you are not identical to your siblings.

33. $500 Answer from Meiosis phases What is crossing over during Prophase I of Meiosis, where alleles are exchanged in tetrads during gamete formation. This leads to genetic variation.

34. $100 Question from terms, terms What is created at the end of mitosis?

35. $100 Answer from terms, terms What are two daughter cells.

36. $200 Question from terms, terms What pulls sister chromatids apart and where does it attach to?

37. $200 Answer from terms, terms What is- spindle fiber, it attaches to the centromere.

38. $300 Question from terms, terms How do bacterial cells divide?

39. $300 Answer from terms, terms What is- binary fission?

40. $400 Question from terms, terms What is the difference between sexual and asexual reproduction?

41. $400 Answer from terms, terms What is- asexual reproduction is when an organism makes a clone of itself by copying its own DNA exactly. Sexual reproduction is when male and female DNA must combine to form a fertilized egg.

42. $500 Question from terms, terms Unscramble the following: Prophase I, G2, Metaphase II, Anaphase I, S, Telophase II, cytokinesis I, cytokinesis II, Anaphase II, G1, metaphase I

43. $500 Answer from terms, terms What is: G1, S, G2, prophase I, metaphase I, anaphase I, telophase I, cytokinesis I, metaphase II, anaphase II, telophase II, cytokinesis II

44. $100 Question from random During which part of the cell cycle does the cell spend most of its time and why?

45. $100 Answer from Random What is- interphase, because it needs a lot of time to grow and perform its normal functions.

46. $200 Question from Random What happens when a cell continuosly to divides unchecked?

47. $200 Answer from Random What is cancer/ tumor.

48. $300 Question from Random What is the difference between identical and fraternal twins?

49. $300 Answer from Random What is- identical twins come from the same fertilized egg whereas fraternal twins come from two eggs fertilized at the same time.

50. $400 Question from Random What is one thing that can happen when you have trisomy or monosomy in your karyotype?

51. $400 Answer from Random What is a genetic disorder, such as Turners syndrome, Down’s syndrome, Trisomy 13, Klinefelter’s syndrome

52. $500 Question from Random What might account for a genetic disorder? (i.e. what and where could something have gone wrong?)

53. $500 Answer from Random What is- a mistake could have occurred when chromosomes line up during metaphase I or metaphase II or the splitting up of the tetrads or chromosomes could have gone wrong during anaphase I or anaphase II.
