Could the shape of DNA give it electromagnetic amplifying properties like a radio receiver?

Question

namely the compounding phone cord-like coiling.

Answer 1

Sorry dude, if you feel that you are receiving signals, then you may need a neurologic check :-)

All joking aside, however, the carbon backbone of the DNA molecule is not a conductor.   You need to have a conjugated system with alternating (resonance) double bonds to conduct, which DNA doesn't have.  Carbon nanotubes might fit this description and might have some interesting electrical properties.  But even then, antennae don't amplify radio signals, they just resonate at certain frequency proportional to their length and so they capture the resonant frequency, and then your radio has a powered amplifier that boosts the signal so that you can hear it.  So even if your DNA could resonate at a radio frequency, which it most likely doesn't, you would still need some sort of amplifier to make that signal useable.

Also, a coiled conductor would have  impedence proportional to its amount of coiling--I'm not sure what that would do to a receiver, but even though an outstretched DNA molecule could be the right length for radio reception, I think that coiling it up into a little microscopic chromosome would totally change its properties, most likely not making it receive in the radio frequency anymore.
