I just found out that can my professor speak five languages.

The conjugate acid OH- of  is ________.

Rick’s three-year-old son, Brian, is particularly fearful.  Give Rick four suggestions for helping Brian deal with his fears.

A unicellular eukaryotic microorganism is isolated from a patient with gastrointestinal symptoms. It is heterotrophic, lacks a cell wall, and moves using flagella. Which group does this organism most likely belong to?

There is nothing to turn in for this question. After submitting this exam and closing down the Honorlock software, e-mail a screenshot(s) of your scratch paper to ammains@umary.edu.  I will use the work on your scratch paper to provided partial credit if needed.

The process of learning to get along with others is called .

The fear of being away from familiar people and places is known as anxiety.

(4 pts) Which would you expect to be higher, the RWork or RFree of a crystal structure? Why? 

(2 pts) Where on the below diffraction image would you expect to find the reflections that correspond to the highest resolution data? 

(12 pts) The chemical shift is one of the most important experimental NMR parameters which becomes readily available at a very early stage of a protein NMR study. Amino acid chemical shifts are determined by the corresponding covalent structure (identity of amino acid; e.g. Gly vs. Ala or atom in an aromatic sidechain vs. atom in an aliphatic sidechain), the neighboring amino acids (flanking in the primary sequence), interactions with other amino acids through space (e.g. spatial vicinity in a folded protein). Shown below are the “fingerprint” 2D 1H-15N HSQC spectra of a protein acquired under two conditions (A and B).     a) The resonances of which exactly atoms are correlated in a 2D 1H-15N HSQC experiment? (4 pts)   b) Which of the two conditions (A and B) corresponds to non-native conditions (9M urea) and which to native conditions (0M urea)? Justify your answer (8 pts)
