The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.

- San Andreas Transform Boundary Plate Motion The geologic map below of southern California shows the position of the famous San Andreas Fault, a transform plate boundary between the North American Plate (east side) and the Pacific Plate (west side). The relative motion between the plates is indicated by the half arrows along the transform plate boundary (i.e., the Pacific Plate is moving to the northwest relative to the North American Plate). Note the two bodies of Oligocene volcanic rocks (labeled Ov) on the map in the previous page located along either side of the San Andreas Fault. These rocks are about 23.5 million years old and were once one body of rock. They have been separated by displacement along the fault. 21. Based on the offset of these volcanic rocks, what is the average annual rate of relative plate motion in cm/yr?
