OnScreen DNA Lite by OnScreen Science, Inc.

OnScreen DNA Lite gives everyone a "painless" way to grasp the details of the double helix structure of DNA. This is accomplished by on-screen tutorials that guide you through an exploration of a virtual 3D model. In addition, there is a simulation of DNA denaturation, a laboratory phenomenon important in biotechnology, in which the DNA strands are seen to split apart. These two activities are taken from more advanced editions of the software.
