RasMol and Chime: Molecular Visualization Freeware

Highly recommended. Download and install the Chime plug-in and you can look at DNA as you've never seen it before. Chime is a program that allows you to rotate, move and look at molecules in your web browser.

Access Excellence

As part of their archives on favorite classroom activities submitted by high school biology and life sciences teachers, the transcript of an interview with Dr. Francis Crick is available.

LionBook Web site

Developed by the authors of Biology, the Living Science, this web site has the Watson and Crick paper: A Structure for Deoxyribose Nucleic Acid, and also A Reader's Guide to James D. Watson's The Double Helix. There are also interesting essays on the process of scientific discovery.

Crystallography 101

This site is from Dr. Bernhard Rupp's lab at the Lawrence Livermore National Laboratory, and has a tutorial on X-ray crystallography.

Left-handed DNA Hall of Fame/Wall of Shame

This web site is maintained by Tom Schneider at the National Institutes of Health. As he says, "many artists will flip a picture of DNA over and reverse the twist [from right-handed to left-handed]... This error has become so pervasive that even well-known scientists, major scientific journals and institutes make it." His web site has a collection of these mistakes.
