Carl has just finished purifying a protein and analysis by gel filtration indicated that the molecular weight of the native (undenatured) protein was 130,000 dalton. His advisor wanted him to determine whether this protein had quaternary structure using gel electrophoresis. He wants to be able to describe the molecular weight of each of the subunits and the forces involved in linking these subunits together (disulfide linkages and/or electrostatic, hydrogen bonding and hydrophobic interactions). Carl first analyzed his pure protein sample...

In high school, Jake had been a tall and well-coordinated student who was sought after by his school’s sports teams. He’d played on both the football and basketball teams. In his second year of college now, Jake came to the Student Clinic because of a sprained wrist. This gave the nurse an opportunity to do a complete history. In the course of the history, Jake mentioned that he felt clumsy compared to his high-school-athlete self. He was a large and...
