DNA Timeline/ Model Project Objectives: 1. Construct a timeline of scientists and their contributions to the discovery of the structure and function of the DNA molecule (30 pts) 2. Construct a model of DNA, using any materials, that is at least 12 base pairs long. For objective 1, include the following scientists: (3 pts for each scientist) Gregor Mendel Friedrich Miescher Frederick Griffith Oswald Avery Erwin Chargaff Rosalind Franklin Alfred Hershey and Martha Chase James Watson and Francis Crick Frances Crick (Central Dogma Idea) Marshall Nirenberg Write 3-4 good sentences (IN YOUR OWN WORDS) describing each scientist’s contribution to the discovery of the structure and function of DNA For objective 2, include the following: A. With your partner, create, using the available resources, a model of the DNA molecule that has the following: (30 pts) Present Absent 1. 24 nucleotides 1. 2. 12 base pairs 2. 3. 1 twist 3. 4. 7 thymine 4. 5. 7 adenine 5. 6. 5 guanine 6. 7. 5 cytosine 7. 8. 24 deoxyribose 8. 9. 24 phosphate 9. 10. 12 hydrogen bonds 10. between base pairs B. Create a KEY to identify each piece/part of your model. (5 pts) C. Neatness. (5 pts)
