Overview
The diffraction of DNA is a famous example of an important life science technique based on physics principles. This demonstration conceptually describes how the characteristic patterns in the image indicate the structure of B-DNA. Biological molecules are being identified today using this technique, and are inventoried at the Protein Data Bank.
