Choose the correct description/statement about gluten from the list below.
| Gluten is a kind of carbohydrate molecule, which is why it is found in grains and other starchy foods. |
| Gluten is found in all fruits and vegetables. |
| As long as a food contains no wheat, it is gluten-free. |

| People with celiac disease should avoid gluten-containing grains like quinoa, millet, and corn. |
Elizabeth is seated with her friend at her favorite restaurant. It’s the first time she has eaten out after beginning her new diet. She wants to be sure to choose gluten-free items from the menu. She orders sparkling water with lemon and the grilled salmon with sautéed kale and mushrooms. The waiter reminds her that she can choose one more side dish.
Which of the following side dishes is gluten-free and, therefore, safe for Elizabeth to eat?

I am currently studying experimental analytical assays such as:
1. deletion analysis + reporter assay
2. linker scanning mutation assay
3. DNase I foot-printing assay
4. Electrophoretic mobility shift assay
5. ChIp-Seq
And I would like to look further into the applications of these methods. I am particularly comfortable with (1), (3), and (4) so any suggestions on an experiment I could test would be much appreciated. Not looking to do anything too complex but just something interesting and simple. I know that this isn't the typical homework question, but we do have to write about a paper about such an experiment that uses one of these methods.

Hermione is using a combination of glyburide and pioglitazone for the treatment of type II diabetes. Her condition is stable as she remains relatively compliant with her treatment. At her bachelorette party, she drinks a more than what she is used to, and faints soon after thereafter. Before fainting she experienced an elevated heart rate and confusion. She is rushed to the hospital, where they administer IV glucose and dextrose. Regarding the presentation, i) explain the underlying reasons leading to her fainting, and ii) why she received glucose as emergency treatment.
