X-ray crystallography is by far the most widely used method to determine atomic-resolution structures of biopolymers but is limited to samples that form well-ordered, three-dimensional crystals.

Simultaneous equations are two linear equations that can be solved using bar models. By remembering that the same letter will always have the same value we can work out the missing values. To solve ...
