Virologist Ed Rybicki of the Department of Microbiology at the University of Cape Town, South Africa, has put together this tutorial on molecular virology. Designed for second year college students, the tutorial provides a colorful introduction to the topic. Basic text is hyperlinked to detailed explanations, giving viewers an opportunity choose the level of detail with which they want to explore molecular virology. The site covers the basics (What is a Virus?) through more complex virology (e.g., Virus Architecture, Genomic Replication Strategies of Viruses, and Virus Classification). Although slightly awkward in navigation (some pages are slow to load, and font size and color can be distracting), the content of the site is well worth the read, and educators will find much useful material here.
