  1. Communities and EcosystemsJEOPARDY!! 

  2. 10 Discovery of DNA Which scientist discovered the presence of a transforming factor while working with mice and pneumonia-causing bacteria?

  3. 10 Discovery of DNA Griffith

  4. 20Discovery of DNA Using the conclusions of Griffith’s experiment, which scientists discovered DNA to be the hereditary material?

  5. 20 Discovery of DNA Hershey and Chase

  6. 30Discovery of DNA Using models and the research of various other scientists, what were Watson and Crick able to discover?

  7. 30 Discovery of DNA The structure of DNA, and thus were able to hypothesize DNA replication

  8. 30 Community 1

  9. What two macromolecules were suggested to be the transforming factor, and how were they distinguished from one another in Hershey and Chases experiment? 40Discovery of DNA

  10. 40 Discovery of DNA *DNA- phosphorus*Protein-Sulfur

  11. What were the results of Griffith’s experiment? 50 Discovery of DNA

  12. 50 Discovery of DNA Heat-killed pathogenic (harmful) bacteria mixed with living non-pathogenic (harmless) bacteria caused the formation of living pathogenic (harmful) bacteria.

  13. 10 The monomers of the nucleic acids are called… DNA structure and replication

  14. 10 Nucleotides DNA structure and replication

  15. 20 DNA structure and replication Identify two differences between DNA and RNA.

  16. 20 DNA structure and replication *DNA –thymine, deoxribose, double stranded, longer*RNA- uracil, ribose, single stranded, shorter

  17. 30 DNA structure and replication Two polynucleotide strands are held together by 1._______ bonds, and the backbone of each strand is held together by a 2._______.

  18. 30 DNA structure and replication 1. hydogen2. covalent

  19. 40 DNA structure and replication DNA Polymerase cannot start a new polynucleotide chain, but can only extend one. What is required to mark the start? *be specific*

  20. 40 DNA structure and replication *an RNA primer laid down by RNA primase.

  21. 50 DNA structure and replication DNA polymerase can only make a new strand in one section and why?

  22. 50 DNA structure and replication 5’3’; DNA polymerase can only attach to the 3’ –OH of the deoxyribose sugar at the end of the template.

  23. 10 DNA Replication and the Cell Cycle Which enzyme unzips the DNA molecule?

  24. 10 DNA Replication and the Cell Cycle Helicase

  25. 20 DNA Replication and the Cell Cycle Why is DNA replication considered semi-conservative?

  26. 20 DNA Replication and the Cell Cycle One of the original strands of DNA is retained (“conserved”) in the newly constructed strands.

  27. 30 DNA Replication and the Cell Cycle What is the order of the Cell Cycle?

  28. 30 DNA Replication and the Cell Cycle G1SG2MCytokinesis

  29. 40 DNA Replication and the Cell Cycle Johnny smokes cigarettes. The DNA of Johnny’s body has become mutated due to exposure to nicotine. He no longer contains the correct gene instructions to make certain surface proteins on his cells. What could happen as a result?

  30. 40 DNA Replication and the Cell Cycle • The cells will not recognize one another, will continue to divide although bumping into each other, and a tumor can form.

  31. 50 DNA Replication and the Cell Cycle *What are the role of checkpoints in the cell cycle?

  32. 50 DNA Replication and the Cell Cycle *help to ensure phases of the cell cycle are complete and accurate before moving on to the next phase.

  33. 10 Mitosis What are the phases of mitosis?

  34. 10 Mitosis • Prophase, Metaphase, Anaphase, Telophase

  35. 20 Mitosis What kinds of cells are produced through mitosis? BE SPECIFIC

  36. 20 Mitosis Diploid somatic cells (non-sex cells)

  37. 30 Mitosis Identify the phase and briefly explain.

  38. 30 Mitosis Prophase; chromosomes appear, nuclear membrane disappears, spindle fibers form

  39. 40 Mitosis What are the differences between plant and animal mitosis?

  40. 40 Mitosis *no centrioles are used in a plant cell during mitosis (spindle fibers form spontaneously) *plant forms a cell plate, instead of a cleavage furrow, during telophase leading into cytokinesis

  41. 50 Mitosis A fungus has a diploid number of 30. Fungal haploid cells have the ability to continue through the cell cycle and perform mitosis (undergo all stages of the cell cycle including Interphase). If this haploid cell went through mitosis, hat would the number of chromosomes be during prophase? What would the chromosomes look like?

  42. 50 Mitosis 15; X shaped chromosomes

  43. 10 Meiosis My name is Bond, Ionic Bond;Taken, not shared!

  44. 10 Population Growth From: Mariano Cecowski <MCecowski#NoSpam.sif.com.ar>Q: if both a bear in Yosemite and one in Alaska fall into the waterwhich one disolves faster?A: The one in Alaska because it is HIJKLMNO

  45. 10 Population Growth Alimentary: What Sherlock Holmes said to Dr. Watson.Urinate: What a nurse would say if a patient asked her what room he's in.Urine - The opposite of "You're out!"Benign: What we want when we are eight.Intestine - Currently taking an exam CARDIOLOGY: advanced study of poker playing TERMINAL ILLNESS: getting sick at the airport

  46. 10 Meiosis What term is used to describe chromosomes that carry the same genes, just different versions of those genes?

  47. 10 Meiosis Homologous chromosomes

  48. 10 Population Growth

  49. 20 Meiosis When do homologous chromosomes pair up? What happens as a results?

  50. 20 Prophase 1- synapsis occurs, a tetrad forms, enabling crossing over. Meiosis
