Feedback for Multiple Choice Quiz 8 #2

  All of the correct answers have a green check mark.
  Incorrect answers have the "red-lit" button next to your choice.
  1. The incorrect statements are a mix of false or true, but irrelevant comments that are not conclusions from the experiment.

  2. Urea will denature most proteins. The point of the disulfide reduction/reoxidation was to show which bonds reformed following the renatuation step.

  3. Showing that the original native structure was regained (against all odds) following renaturation was crucial. The identity of the reformed S-S bonds proved this point.

  4. The correct answer is surrounded with silly statements!

  5. The incorrect statements are mostly false or irrelevant minutiae. The correct answer either required some thought or should stimulate some about what trypsin does to proteins.

  6. Refolding to the native conformation decreases the entropy of the protein and does nothing to the primary structure.
