STUDY QUESTIONS FOR WEEK 1: 1. What are the defining characteristics of prokaryotic and eukaryotic cells? 2. Biochemistry has shown that humans, yeast, and plants are actually quite similar despite vast differences in outward appearance. What is this based on? 3. Draw a hydrogen bond that is present in the cell? Which is the hydrogen bond donor? Which is the hydrogen bond acceptor? 4. Explain how van der Waals interactions can be called a “team effort”. 5. Draw the van der Waals interaction graph and note the van der Waals contact distance. What is the van der Waals contact distance? 6. Discuss how the various bonds/interactions explained in lecture take part in the structure of DNA double helix. 7.

Find the pH of 1.25 M acetic acid and 0.75 M potassium acetate. 11. Calculate the pH of a buffer solution made from 0.20 M HC 2 H 3 O 2 and 0.050 M C 2 H 3 O 2-that has an acid dissociation constant for HC 2 H 3 O 2 of 1.8 x 10-5 . Solve this problem by plugging the values into the Henderson-Hasselbalch equation for a weak acid and its conjugate base. 12. How does X-ray crystallography lead to a prediction of the 3-D structure of a protein? 13. What are various ways that gene expression can be affected? 14. Why are some shar-peis wrinkly and some are not?...
