家园 gene stability,mutation

"This time it is easy to see that the energy gaps between the electronic levels are huge compared to the vibrational and rotational levels.

At room temperature, The large energy gap between the first electronic level and the next nearest level practically guarantees that all hydrogen molecules (and most other molecules) exist only in their electronic ground state.

1.is this the "gene stability" in Delbruck's model ?

2. on the other hand,mutation etc, door of opportunity is still wide open:

"It is, however, more likely that many molecules exist in different excited vibrational or rotational states"

also, indeterminacy induced

"enhancing the purely accidental nature in mutation, meiosis, and so on"

mind body, chinese tricks, soul, god..why not?

Schrdinger wrote that, contrary to the opinion held by some physicists, quantum indeterminacy plays no biologically relevant role in the space-time events in the body of a living being, except perhaps by enhancing the purely accidental nature in mutation, meiosis, and so on.

"Molecules can be made to jump between different energy levels, electronic, vibrational and rotational, by applying different frequencies of light. If the energy of the light matches the energy gap of the energy levels (among other criteria ... selection rules) then we may get an absorption pattern (spectrum) that can be used to uniquely identify the molecule."
