I had a problem with the word "bandwidth", which has a precise meaning in the context of signal processing, but seems vague when applied to DNA. The only thing that comes to my mind as a clearly quantifiable "bandwidth" is the rate at which purines and pyrimidines pass out of a nucleus. It doesn't seem like a terribly interesting quantity. It also ignores environmental factors. -- - - - - - - - Christopher Ian Connolly connolly@cs.umass.edu Laboratory for Perceptual Robotics wa2ifi University of Massachusetts at Amherst Amherst, MA 01003
