- Call it anything you want. 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.

- 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.
