While this is true, it overlooks the selection pressures that exist on nucleotide selection. If I recall correctly, the canonical bases are relatively robust to radiation in the ir, visible, and uv spectrums when compared to other nucleotides.

Not sure if that's the correct article, but it's a good starting point on selection pressures for nucleotides and heterocycles. That is to say - just because visible light is more energetic does not mean it is guaranteed to cause more damage. (I briefly worked in Tor's lab - a truly incredible chemist and teacher) |
