Course Outline
The Course will be broken up into three parts:
(1) Principles of X-ray crystallography.
(2) Macromolecular structures.
(3) Student presentations.

Grading will be based on the following: There will be problem sets (10%) and a mid-term exam covering part 1 (30%), and a final exam covering parts 2 and 3 (30%). For part 3 of the course, students will also be required to make a 20-30 minute presentation on a manuscript describing a macromolecular structure of their choice (30%).

Tentative Schedule - September 11, 13, 18, 20, 25, 27; October 2, 4, 9, 11, 16, 18, 23, 25 (Exam)
