More Evidence of Quantum Behavior at Biological Scale: Proton Tunneling in DNA

By Inés Urdaneta / Physicist and Research Scientist at Resonance Science Foundation

Former RSF articles had addressed quantum effects that have been observed in biology, more precisely, in the microtubules, giving plausible support to the fact that biology, just as consciousness, could have a quantum origin.   

Now, a paper published in the journal Communications Physics, entitled An open quantum systems approach to proton tunnelling in DNA,  is shedding light on the physical mechanisms that might cause the protons to jump across between the DNA strands.

The DNA strands usually depicted as two double helices, are composed of molecules named nucleotides, which organize in two strains to form each of the helices, as depicted below:
