Good one! Floating proteins come wiggling in from afar and find their docking site. Now I recall I first encountered the topic around 1985, when trying to build a museum exhibit device to demonstrate an active site on a molecule: a set of magnets in a pattern, and a corresponding set of opposite magnets. There was no attraction until a tiny fraction of a "nanometer." But even if real molecules could attract enzymes from 10X farther, they couldn't "suck in" enzymes from more than a few atomic diameters distance. But in order to function, biochem would need to pull in enzymes from hundreds of atom-diameter distances (if not tens of thousands.) > This textillian version shows the nucleotides swarming into place: > http://www.youtube.com/watch?v=dveIc7svytI > > With all these radio signals in the cell, I wonder what prevents > intermodulation distortion from causing interference? Narrowband transmitters and receivers! VERY narrow band, using high-Q superconducting tuning coils, and no modulation other than the line-splitting of one or more closely-coupled resonators.
