  2. Mitosis • What are the stages of mitosis? • Be sure to discuss the steps of interphase, how many cell(s) you start with, and how many you end with, and the chromosome number in the beginning and in the end.

  3. Answer

  4. Meiosis • What are the stages of mitosis? • Be sure to discuss the steps of interphase, how many cell(s) you start with, and how many you end with, and the chromosome number in the beginning and in the end.

  5. Fertilization • Compare and contrast the contents of an egg and sperm cell.

  6. Answer

  7. Diploid vs. Haploid • What is the difference in a cell that is diploid versus a cell that is haploid. What types of cells would represent each?

  8. Answer

  9. Genetics • Complete a cross on paper for the following types of crosses. Get my signature for approval that they are correct. • Normal Mendellian Cross (Dominant/Recessive) • Cross working backwards where I have to figure out the parents based on your choice of offspring. (Same as above) • Incomplete Dom Cross (3rd new color) • Co-Dom Cross (blood type) • Do phenotype and genotype for all crosses.

  10. Karyotype • What is a karyotype? • What can we see on a karyotype?

  11. Answer

  12. Definitions • Define the following terms: • Chromosome • Homologous set of chromosomes (draw a set and get teacher signature) • Nucleus • gene • Mutation • Replication • Transcription • Translation

  13. Answers

  14. Proteins This chart shows the amino acid chain in a hemoglobin protein. How many differences are there between the human and the baboon?

  15. Answer

  16. DNA/RNA • If one side of DNA was AATTCCGGAATTCCGGAA what would the other side be?

  17. Answer

  18. DNA/RNA • If a mRNA strand was carrying the following code: AUGACCGGUUACCCGUAA, what would the amino acids be in the protein?

  19. Answer

  20. Translation (aka protein synthesis) • Can both prokaryotic and eukaryotic cells carry out the process of translation? • If so, why? How? What steps do they have in common? What would be different?

  21. Answer

  22. Mutations • Draw a normal side of DNA then underneath that show 3 different strands: one with a substitution mutation, then show an insertion, then show a deletion.

  23. Answer

  24. Definitions • Define genetic engineering • Define cloning

  25. Answer

  26. Evolution • Describe how adaptations lead to Natural Selection. Give examples using animals.

  27. Answer

  28. Evidence Of Evolution • Describe how each one of the following can be used as evidence for evolution: • 1. Fossils • 2. Embryology • 3. Anatomy (homologous & vestigial structures) • 4. Biogeography • 5. Molecular Evidence

  29. Answers

  30. Ecology • What are the 5 levels of ecological organization? • Give examples that belong in each. • Define the difference between biotic and abiotic and give examples.
