Oh! Neil, you are so correct. I know the entire universe is just a wave
function but I tend to forget. I look at the circle of life and pick a point
to enter the circle to try to understand it. Silly me, I should have picked
the centrioles. When the centrioles crack the whip, the DNA jumps through
hoops. Let us forget the higher plants and go with the centrioles. The
"machinery of the living cell" consists of molecules, and all molecules are
equal. Still, as was pointed out in Animal Farm, some molecules are more
equal than others.
I am so naive (and so old). Is it possible that the mention of DNA is
politically incorrect? Is that the trouble? Are those worker molecules, the
large and small ribosomal subunits, the real heroes in this tale?
Enough! I am undeconstructed and unreconstructed, I will go to my grave a
reductionist. The DNA constructs the organism by pushing out mRNA. Let us
have no holistic talk about the "living cell".
