The idea I'm speculating on concerns the mechanism by which the nucleus exerts some degree of control on the operation of the cellular machinery. The manufacture of protein being but one step in the chain. The particular question I'm asking, "Is it within the realm of possibility that a large active cell suffers degradation in performance-resilience-etc because of the smaller nucleus to mass ratio. >Put another way: I could write a one-line program that would never >terminate -- it would represent an infinite amount of "computation", >yet only consist of one line's worth of program. So the length of DNA >means nothing in that context (assuming more than just transcription >or similar processes). I'm afraid you've lost me here. One of the things I'm trying to come to a greater understanding of is the intelligence/smarts/computing-power of a genetically controlled cell, or the genetically controlled processes of a whole organism. I suspect that a program of 750 megabytes (the human genome) which has been under development for several billion years probably represents a pretty fair chunk of intelligence no matter how you measure it. -- Ken Easlon ken@holonet.net
