DNA and Bessel functions

Read Original

This article discusses how Bessel functions appear in the analysis of X-ray diffraction patterns from helical structures like DNA. It references the 1952 Cochran, Crick, and Vand paper showing that diffracted amplitude on each layer line is proportional to a Bessel function of the first kind. The post also clarifies that Watson and Crick discovered DNA's structure, not DNA itself, and links to related posts on Bessel functions.
