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.
- The incorrect statements are a mix of false or true, but irrelevant comments that are not conclusions from the experiment.
- Urea will denature most proteins. The point of the disulfide reduction/reoxidation was to show which bonds reformed following the renatuation step.
- 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.
- The correct answer is surrounded with silly statements!
- 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.
- Refolding to the native conformation decreases the entropy of the protein and does nothing to the primary structure.
