Yes, at this point in your study of cell biology, this looks like an aptitude question! (It certainly shouldn't after we've covered cell signaling, however!). Although it seems so foreign, we can examine its structure and talk about how to begin answering it.
1. Don't panic when you encounter something unfamiliar! Seriously...take a deep breath (or whatever behavioral trick works for you) and ask yourself:
  • What's the question asking?
  • What's the question not asking?
  • If you're unsure, ask the instructor for clarification.
  • What information provided is important for answering the question?
  • What information is irrelevant?

So...following these suggestions...

2. What's a hypothesis and what's a mechanism? (Major themes of BI250!)

3. How can you test a hypothesis or determine a mechanism? (Other major themes!)

4. What's relevant information? Read the 1st paragraph carefully, especially the nouns! Begin the answers with what you know; build from a foundation of knowledge.

5. What's irrelevant information? The entire 2nd paragraph! Anything else?

6. Hey, what's irrelevant information doing in a problem or on an exam question? Get real! Most of the problems cell biologists or anyone else encounter contains extraneous information. Being educated means being able to store and sort information, to construct the most likely answers and to test the accuracy of those answers. In short, being able to think...and you need information to think concretely, to think well.

7. BI250 exam questions will test what you should have memorized. Some BI250 exam questions, like this one, will also test how well you can apply what you've learned: how well you can synthesize information, how well you can analyze data, and how well you use what you know to solve unfamiliar problems.

8. The structure of the exam also provides useful information! To some extent, the amount of space provided for the answer and the point value indicate how important a question is. Generally speaking, an answer should not exceed the space provided and you should allow yourself about 1 minute per point to answer BI250 questions: thus, 10 min for a 10 pt. question, etc.
