RasMol Quick Start: tells beginners how to use RasMol, also where and how to download any molecule of interest (large or small) for viewing in RasMol.

What questions can you answer about a protein/DNA molecule with RasMol? Walks beginners step by step thru methods for answering questions including:

How to save selected views of molecules for use in your teaching. This document explains how to use RasMol's powerful save script filename command, and provides troubleshooting if needed.     This document also explains how to create a master script which plays back your RasMol-saved scripts smoothly, in the desired order.

Putting your teaching presentation on the web. Explains how to incorporate your RasMol-saved scripts into a Chime-based presentation on the web. A downloadable Chime template is provided. You need merely change a few lines in it with a text editor -- no programming is involved! An example of such a teaching presentation, showing the gal4 transcriptional regulator complexed to DNA, is provided.

A ready-to-use tutorial on basic DNA structure is designed for self-directed (nonlinear) exploration by students, with an easy-to-use, fun, push-button interface.     Downloadable for local installation.

A 10-minute lecture segment on protein secondary structure (using lysozyme as an example, matched to Campbell's Biology textbook) can be illustrated with a ready-to-run (linear) presentation viewable, then downloadable (for projection from a computer without an Internet connection) from

Web-based visualization tutorials on over 30 other molecules are indexed at the World Index of Animated Tutorials on Biomolecular Structures at

Quelques scripts RasMol ont été traduits en Français par l'Institut National de Recherche Pédagogique de la France. Thèmes d'étude: Structure du tétramère de l'hémoglobine, de ADN, de CMH, et de antigène-anticorps.
