This is a very structured interactive animation about PCR. It has an associated background essay, and some discussion questions. The thing I like about it is that it is an application of transcription. From the site: "In this interactive activity adapted from the University of Nebraska's Library of Crop Technologies, learn the basic steps of polymerase chain reaction (PCR), a technique used to produce short sections of DNA for analysis. In this technique, various components are combined in a microfuge tube and heated in a thermal cycler. The activity details the process, which results in thousands of identical copies of a DNA fragment. Note: The activity provides a simulation of the process. The characterizations of depicted components and their behaviors should not be taken literally."
