Proteins Quiz - Graduate Level Questions

You can study the class notes before you take the quiz.

Question 1 : Which of the following can cause disease?

A. A protein that contains an incorrect amino acid
B. A protein that is incorrectly folded
C. A protein that is missing from the body
D. All of the above

Question 2 : What is structure-based drug design?

A. A rigorous, highly structured way to create new medicines
B. A strategy that relies on the structure of the drug delivery method (tablet, time-release capsule, syringe, nasal spray, etc.)
C. A method of designing medicines that relies on computational models of protein structures
D. All of the above

Question 3 : Which of the follow statements are true about graphic representations of proteins (computer models)?

A. Ribbon diagrams highlight organized regions of the proteins
B. Space-filling molecular models attempt to show atoms as spheres whose size correlates with the amount of space the atoms occupy
C. A surface rendering of the protein shows its overall shape and surface properties
D. All of the above

Question 4 : Why do X-ray crystallographers like to use synchrotrons?

A. Synchotrons generate intense beams of X-rays that can be tuned to the appropriate wavelength
B. Synchrotrons analyze and refine structural data, so scientists don't need computers to do this
C. The X-rays from synchrotrons are much less harmful than traditional X-ray sources
D. All of the above

Question 5 : Why does NMR have an advantage over X-ray crystallography for certain research?

A. It can determine the structures of proteins that are too large for X-ray crystallography
B. Proteins are closer to their natural state in NMR studies, which rely on a solution, than they are in the crystalline form used for X-ray crystallography
C. It is much faster than X-ray crystallography
D. It doesn't require the use of isotopes
E. It shows hydrogen atoms, which do not appear in X-ray crystal structures
