Right - Or even the fact that reaction rates are temperature-dependent.

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.
