![4. Use the cartoon protein below to answer the following questions. Assume the rounder subunits are 45
kDa and the star shaped group is 27 kDa. The lines represent disulfide bonds.
A. What is the size of the native protein?
B. Draw an SDS-PAGE gel for the sample under reducing and non-
reducing conditions. Clearly label the anode and cathode and label the
lane that contains the reducing sample and the nonreducing sample.
