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...

This video compares 1918 flue H1N1 to the current threat: avian flu H5N1. Using animation, the video explains (1) the mechanism of how viruses enter target cells and release from target cells, (2) why 1918 flu named H1N1 and avian flu named H5N1, and (3) why viruses that transmitted only bird-bird can gain the ability of bird-human or even human-human transmit. Biotechnologies such as reverse...
