a.) Proteins A and B with molecular weight of 16,500 and 35,400 move 4.60 cm and 1.30 cm respectively, during electrophoresis and in SDS-polyacrylamide gel. What is the molecular weight of protein C that moves 2.80 cm under the same conditions in the same gel?

b.) The sedimentation coefficient of a DNA molecule is 22.0 S. A dilute solution of the DNA is spun in a centrifuge at 40,000 rpm starting from a distance of 6.0 cm from the axis of rotation. How far will the DNA move in 20 min?

Acetic acid (molecular weight = 60.05 g/mol) and sodium acetate (molecular weight = 82.03 g/mol) can form a buffer with an acidic pH. In a 500.0 mL volumetric flask, the following components were added together and mixed well, and then diluted to the 500.0 mL mark: 100.0 mL of 0.300 M acetic acid, 1.00 g of sodium acetate, and 0.16 g of solid NaOH (molecular weight = 40.00 g/mol). What is the final pH? The Ka value for acetic acid...

The movement of molecular motors depends on the conformational changes that the proteins undergo as they proceed through the cycle of nucleotide binding, hydrolysis, and release. If you were to add a nonhydrolyzable form of ATP to myosin, at what point would you block its movement? How is this similar to or different from adding a nonhydrolyzable form of ATP to kinesin?
