  8. Who discovered the base pairings (A-T & G-C) in the DNA structure?

  9. Erwin Chargaff

  10. Who discovered the double helix shape of DNA using X-ray?

  11. Rosalind Franklin

  12. Who was considered “the father of genetics”?

  13. Gregor Mendel

  14. Who created a model of DNA using Chargaff’s rule and Rosalind Franklin’s X-rays?

  15. James Watson & Francis Crick

  16. What type of plant was used by Gregor Mendel and why did he use them?

  17. He used pea plants because they grow quickly and self-pollinate.

  18. During which phase of the cell cycle does DNA replication occur?

  19. Late interphase

  20. DNA is made of many units called nucleotides. What molecules make up a nucleotide?

  21. Sugar Phosphate Nitrogen base

  22. Which nitrogen bases pair up within the DNA structure?

  23. Adenine with Thymine & Guanine with Cytosine

  24. If 15% of a DNA strand is made of adenine, what percentage of the DNA is made of guanine?

  25. 35% Guanine (because adenine And thymine make up 30%, then guanine and cytosine make up the other 70%).

  26. How does DNA replication occur?

  27. 1. The DNA is unzipped 2. Nucleotides (G, C, A, & T) are used to build a new complementary strand to the original DNA strand 3. Two completely identical strands of DNA are formed

  28. What is the shape of DNA?

  29. Double helix

  30. What are the sides of DNA ladder made of?

  31. Sugars & Phosphates

  32. Daily Double

  33. What is the complementary DNA sequence for the code below? AGTCTTACT

  34. TCAGAATGA

  35. What is a mutagen? Provide three examples.

  36. Anything that causes a DNA mutation. X-ray, UV light, asbestos, cigarette smoke.

  37. What are the three types of mutations? What type causes sickle cell anemia?

  38. Substitution Deletion & Insertion Sickle cell anemia is caused by a substitution

  39. Name the part labeled A in the Diagram. A

  40. Petal

  41. Name the part labeled B in the Diagram. B

  42. Anther

  43. Name the part labeled C in the Diagram. C

  44. Stigma

  45. What are the names of the male parts of the plant? What are they called all together?

  46. Filament & anther, And together they are called Stamen

  47. What are the names of the female parts of the plant? What are they called all together?

  48. Stigma, style, and Ovary (with ovule), together they are called a Pistil

  49. If two heterozygous orange tigers mate (with the white allele being a recessive), what will the first generation look like?
