 I often tell medical students that, you know, the perception that you might have had of a gene would be as a very well-defined and discreet entity that if you could sort of miniaturize yourself at the level of a DNA base, let's say, and walk the streets of the genome, you would know when you came to a gene it would be a recognizable edifice. And I don't think it's anything like that. I think if you could miniaturize yourself that way and walk through the genome virtually anywhere, you would have the feeling of being sort of a New York City on New Year's Eve at Time Square.
