HAPPY WEDNESDAY DNA Vocabulary Quiz TOMORROW! Bellwork: Draw and Label 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. Franklin’s X-ray image Watson & Crick’s DNA model Essential Question: What are the components of DNA. 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. Folding Instructions • • • • • • • Small Group CHAMPS Hot-Dog Fold FOLD BOLDED LINES ONLY!!!

Is the number of T bases the same or different? Why? • What kind of bond holds the bases together?
