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.
