Crick, Watson, and Franklin: The Race to Discover the Structure of DNA -By Cynthia Stokes Brown 1. Read the article 2. Read to each circled number and answer the question on the handout in complete sentences. 3. If there are 3 lines – then 2 complete sentences. If there are 6 lines – then 5 complete sentences. If there are 5 lines – then 4 complete sentences. Theory of Relativity / Atomic Bomb X-ray crystallography Rosalind Franklin / Watson & Crick Franklin’s X-ray image Watson & Crick’s DNA model Let’s build a DNA molecule…. DNA Origami • The bases on the right (from top to bottom) are: GAGCAGTGTGT. • The bases on the left (from top to bottom) are: CCTCGTCACAC • You need to find the complementary base pair • Remember to color on the diagonal (as shown below)—only do half, the other half is the complementary base pair G A T C The colors are not correct, so use the key on the previous slide. But put the “letters” in the correct spot, color the correct diagonal, and cut out the square. DNA Model Questions • What are the 3 components in a nucleotide? • What are the components of the DNA backbone? • How many A bases are in your model? Is the number of T bases the same or different? Why? • What kind of bond holds the bases together?
