  1. Keystone Review Module 2: Continuity and Unity of Life

  2. Round 1:Cell Growth and Reproduction

  3. Question #1 Which statement best describes a difference between mitosis and meiosis? Meiosis is a multi-step process Mitosis occurs only in eukaryotic cells Meiosis is used in the repair of an organism Mitosis produces genetically identical daughter cells

  4. Question #2 During which phase of meiosis are sister chromatids pulled apart?

  5. Question #3 What phase of mitosis is shown here?

  6. Question #4 What 3 phases of the cell cycle make up interphase?

  7. Question #5 What is the purpose of mitosis and cell division?

  8. Question #6 What is nondisjunction?

  9. Question #7 In which phase of the cell cycle does DNA replication occur?

  10. Question #8 What is the difference between haploid and diploid?

  11. Question #9 What is a tumor?

  12. Question #10 In which phases of mitosis would you see X shaped chromosomes?

  13. Round 1 Answers D Anaphase II Metaphase G1, S, G2 Produces more cells for growth, repair and differentiation When sister chromatids fail to separate- results in a cell with too many chromosomes S phase (synthesis) Diploid- two full sets of chromosomes, somatic cells, Haploid- only one set of chromosomes, sex cells or gametes 9. Mass of cancer cells Prophase and metaphase

  14. Round 2:Genetics

  15. Question #1 A son gets the Y chromosome from which parent?

  16. Question #2 The actual appearance or feature that is shown for a trait is called the ________________

  17. Question #3 The actual alleles an organism possesses for a trait is called the _______________

  18. Question #4 If the parental genotype for two traits is AaBb what gamete combinations are possible?

  19. Question #5 1 pair of the human chromosomes are the sex chromosomes. What are the other 22 pairs of human chromosomes called?

  20. Question #6What type of chromosome mutation is illustrated below?

  21. Question #7 Which type of trait typically forms a bell-curve when graphed?

  22. Question #8 If one parent has blood type AB and the other parent has blood type O what are the possible blood types for their child?

  23. Question #9 When homologous pairs exchange parts of their chromosome it is called ______________

  24. Question #10 Down Syndrome is caused by a chromosomal abnormality called…

  25. Question #11 What inheritance pattern is it?: Neither allele truly dominates and the heterozygous shows a mix of both traits

  26. Question #12 Because an individual can inherit an A, B or O allele from each parent this type of trait is called ________________

  27. Question #13 Colorblindness and hemophilia are both examples of this type of trait.

  28. Question #14 In this type of trait neither allele overpowers the other and the heterozygous shows BOTH phenotypes

  29. Question #15 What is the probability that these parents will have a child with B blood type? Parents: AO x BO

  30. Round 2 Answers: 1. His father 2. phenotype 3. genotype 4. AB, Ab, aB, ab 5. autosomes 6. translocation 7. polygenic 8. Type A or type B (AO, BO) 9. Crossing over 10. Nondisjunction (trisomy 21) 11. Incomplete dominance 12. Multiple allele trait 13. X-linked or sex linked 14. codominant 15. 25%

  31. Round 3:DNA, RNA and Protein Synthesis

  32. Question #1 A sequence of DNA that codes for a protein and thus, determines a trait

  33. Question #2 Name 3 differences between RNA and DNA

  34. Question #3 How do the nitrogenous bases pair up?

  35. Question #4 A ____________ is a set of three nucleotides that codes for a specific amino acid.

  36. Question #5 Both eukaryotes and prokaryotes perform protein synthesis. Prokaryotes, however, do not have a nucleus. Where does transcription take place in a prokaryote?

  37. Question #6 A genetic mutation occurred in a gene but the correct protein was still created. What kind of mutation is this?

  38. Question #7 During this process mRNA is read and a polypeptide chain is formed.

  39. Question #8 When DNA from one organism is incorporated into the DNA of another organism the resulting DNA is called…

  40. Question #9 The process of synthesizing mRNA from a DNA template is called __________________

  41. Question #10 When a mutation in the DNA causes every subsequent codon to be read wrong it is called a _____________

  42. Round 3 Answers: 1. gene 2. RNA- contains uracil, sugar is ribose, single stranded, 3 kinds DNA- contains thymine, sugar is deoxyribose, double-stranded 3. Adenine- thymine, cytosine- guanine 4. codon 5. In the cytoplasm 6. Silent mutation 7. translation 8. Recombinant DNA 9. Transcription 10. frameshift

  43. Round 4:Evolution

  44. Question #1 Inherited traits that allow an organism to fit better with in its environment are called _______________

  45. Question #2 What did Darwin notice about the organisms on the different islands of the Galapagos??

  46. Question #3 The formation of a new species

  47. Question #4 Random changes to a gene pool in a small population.

  48. Question #5 When something prevents organisms of the same species from reproducing they are experiencing …

  49. Question #6 Environmental factors determine which organisms will get to survive, reproduce and pass on their traits based on their fitness

  50. Question #7 All of the alleles that exist within a certain population
