View Resource HIV Resistance

This 3D animation explains in detail how and why HIVs develop drug resistance in a short period of time.
View Resource NOVA scienceNOW - RNAi (RNA interference)

This video explains DNA transcription, translation, and RNAi inhibition in a very interesting animation/analogy, which should be especially helpful for non biology majors. The application of RNAi in disease treatment (although the treatment seems to be in experimental stage) and the usage of RNAi in gene function identification are explained. The RNAi mechanism is explained in two ways...
View Resource Retroviruses and viral diversity

This interactive slide show includes a brief discussion of what makes a virus a retrovirus, and how they differ from other types of viruses.
