Q14:2. A DNA polymerase is isolated and found to have an error rate of 1 in 106. (6 points, 3 each) A. Suppose that the error rate is determined solely by the relative stabilities of incorrect and correct base pairs. What would the difference in free energy between correct and incorrect nucleotides incorporated by the polymerase have to be in order to explain the error rate? B. Solution studies of isolated oligonucleotides indicate that the energetic difference is actually -1.2 kJ.mol-1. What is the equilibrium constant of correct-incorrect base pair discrimination based on these solution studies?See Answer
Q15:3. The direction of RNA synthesis was determined by growing bacteria for a short period of time with trinucleotides labeled with tritium (³H) on their bases. The structure of RNA looks like : 5' pppNpNpNpNp...N-OH 3' (N = nucleosides; p = phosphates). Cleavage of RNA by a base occurs after the 3' phosphate. (8 points, 2 each) A. What products are produced if RNA is digested with a base? B. The products obtained in Part A can be distinguished by thin layer chromatography.

Q16:4. Reto is an aspiring medicinal chemist whose project involves screening a library of compounds to find molecules that bind with high affinity to the opioid receptor (a membrane protein). Based on our discussion of the thermodynamics of binding, answer the following questions (10 points) A. Reto titrated a candidate compound C (fluorescently tagged) against the purified receptor and obtained the isotherm below. Reto concluded that he found a high affinity specific binder. Is Reto's conclusion correct? Why or Why not? What is missing from the experiment? (2) 1/Fluorescence polarization 450 400 350 300 250 200 150 100 50 0 0 10 20 30 40 [Ligand] (n) 50 60 70/nB. After performing the required controls, Reto obtained the following binding isotherm (left) and the associated Scratchard plot (right). What is the value of K, for the interaction between C and the receptor? What is the total protein concentration used in this experiment? (2) Binding isotherm Scratchard plot 1/Fluorescence anisotropy 300 250 200 150 100 50 0 0 10 20 30 40 [Ligand] (nM) 50 60 [bound ligand]/[free ligand] 0.6 0.5 0.4 0.3 0.2 0.1 0 1 2 3 4 bound ligand [L]bound (nM) in 6/nC. Next, Reto performed the affinity measurements on mammalian cells that express the opioid receptor. He is surprised to find that the K, from these measurements is over 10-fold higher than what he measured with the purified protein. Can you speculate a possible reason that could explain this observation? D. Given the poor affinity of the compound C, Reto modified the library, rescreened and found a candidate molecule R that binds the opioid receptor with a K, of 2nM. A high throughput measurement of binding isotherms of R and other receptors revealed that R also binds to the glucagon receptor with a K₁ of 5 μM. Based on this data, what should be the concentration of R that Reto should recommend for further testing of the compound R in vivo (i.e. in a living human body)? (2)/nE. In an in vitro experiment with R and the opioid receptor, what is the fractional saturation of the receptor, when the concentration of R is 200 nM? (2)See Answer
