X-Ray Crystallography

Below you will find two videos about x-ray crystallography. Please watch both videos. Then watch them again while writing your response (below). 

HW Questions:

1. In your own words what is an x-ray?
2. In your own words, what is diffraction? Give an example.
3. What are angstroms? Explain in your own words and give an example from the book. 
   
4. What steps must be followed when performing x-ray crystallography? (Place the steps in order with at least one line between each step)
   
5. What is the importance of each step in the process? (Write the importance in a different color, next to the step - this is why you saved one line between each step)
   
6. What discoveries have been made because of x-ray crystallography? Please list at least 3 discoveries. 
7. List at least 3 protein structures mentioned in Double Helix?  (give the name of the protein, why it is important and who was working on it). 
8. What are three follow up questions that could help you understand more about this process?
