1 Chapter 9 1. Do I know why cells cannot continue to grow larger and larger? 2. Do I know what phase cells spend most of their time in? 3. Mitosis is the division of the. 4. Interphase is divided into three stages: (name them) 5. The longest stage of mitosis is. 6. Cytokinesis is the division of the. 7. Once the cell cycle begins, there are built in that can stop it any time. 8. If cells do not respond to the normal mechanisms that control cell division, results; do I know what this is caused by? 9. During development some cells go through a programmed cell death called. 10. cells are unspecialized cells that can develop into specialized cells under the right conditions. 11. A chromosome consists of two. 12. In the virtual lab the cancer cells had the highest mitotic index and seemed to show the most aggressive growth. 13. By the end of prophase what has occurred? 14. What happens to the chromosomes in telophase of mitosis? 15. Do I know the phases of mitosis ( picture and what occurs in each phase, and their durations) 16. Which of the cells depicted in the line graph below are most likely cancerous? What has happened to the others?
2 17.. Do I know how many chromosomes a daughter cell will have if it starts out with 12 chromosomes? 18. What are the ways to identify a plant cell vs. an animal cell? 19. Do I know what the cell cycle is regulated by? 20. Do I know which phase cancer cells spend very little time in? 21. Why is the synthesis (S phase) of the cell cycle called this? 22. What phase does DNA replication occur in? 23. The typical growth period of a cell occurs during which stage of the cell cycle? 24. The first three phases of the cell cycle are collectively known as: 25. Do I know why cancer is relatively rare even though they say we get cancerous cells frequently? 26. Prokaryotes divide by binary fission describe binary fission: Chapter Can I describe a gene? 28. How is an allele described? 29. Do I know what Crossing over is and when does it occur? 30. What causes genetic recombination? 31. Do I know how many chromosomes are found in the human body? 32. Do I know the differences between Meiosis I and II - how the chromosomes move and the end results?
3 33. What is formed as a result of mitosis? 34. Can I describe and or illustrate a trait using these terms: dominance, recessive, heterozygous, homozygous 35. Do I understand probabilities and ratios in genetics? For example what is the probability that a cross between a heterozygous dominant yellow-seeded pea plant and a green seeded pea plant will produce green-seeded offspring? 36. What is the number of chromosomes in a haploid cell? 37. What event occurs during Meiosis II but not during meiosis I? 38. How is polyploidy defined? 39. What phase of Meiosis I do the following occur in: chromosome number is reduced from 2n to 1 n = two sister chromatids reach opposite poles of the cell= Homologous chromosomes become visible, condense and form pairs = DNA is replicated= Homologous pairs of chromosomes line up on the equator= 40. What is a homologous chromosome? 41. Do I know how to do a monohybrid cross and figure ratios, phenotypes and genotypes from the cross results.? 42. Do I know how to do a dihybrid cross and figure ratios, phenotypes and genotypes from the cross results.? 43. Can I match the following to the correct Meiosis I phase: Crossover can occur frequently = Proteins are synthesized= Spindle fibers guide separated homologous chromosome pairs toward opposite poles= Homologous pairs line up at the equator = Chapter Can I match the human genetic disorder to its description Albinism Huntingtons disease
4 Tay-Sachs disease Achondroplasia Cystic fibrosis Sickle cell anemia 45. Can I Give an example of incomplete dominance and do a punnett square for a a plant that shows incomplete dominance (snapdragon) 46. What describes the 23 pairs of human chromosomes? 47. A dominant genetic disorder will be expressed if an individual has allele for the disorder. 48. Do I know what a Barr body is? 49. Do I know what the large concordance rates of fraternal and identical twins shows? 50. What is the genotype of a woman with red-green colorblindness? Can I show this using a punnett square? 51. Do I know why Down syndrome is called trisomy 21? Chapter Do I know the two main parts that make up a chromosome? 53.. Do I know purines and pyrimidine s structure & what base each are A + G = T+C= 54. Which base always pairs with guanine? 55. What did Watson and Crick do? 56. What did scientists know about molecular genetics in the early 1900 s? 57..Do I understand the role (functions) of enzymes in replication? (heicase and polymerase) 58. What defines codon in DNA or mrna? 59. What type of mutation causes the DNA replication to stop early? (p 345) What type of mutation is a chemical change in just one base pair? 60. What scientist confirmed that DNA is the genetic material?
5 61. Can I explain how DNA strands fit inside a cell? 62. Do I know what a nucleotide consists of and can I identify them? Which scientist determined the basic structure of nucleotides. (p 329) 63. What is the central dogma of biology? 64. Do I know what the 3 types of RNA are and what they do? ( mrna, rrna & trna)
