This video does a great job of displaying how DNA is organized into chromosomes. The audio description discusses genes with respect to cancer, since it originally came from Emory's www.cancerquest.org. This site has a sequenced collection of interesting short videos on cancer biology (from which this video came), but I have yet to figure out how to get the whole sequence up on the Sift. Until then, this clip offers a good visual aid for the curious on the physical organization of DNA.
