A new study reveals that quantum physics can cause mutations in our DNA

Quantum and classical effects in DNA point mutations: Watson–Crick tautomerism in AT and GC base pairs, Physical Chemistry Chemical Physics (2021). Quantum mechanics is an interdisciplinary field by nature, bringing together nuclear physicists, biochemists and molecular biologists. In the future, we are hoping to investigate how tautomers produced by quantum tunneling can propagate and generate genetic mutations. Although these mutations’ lifetime is short, the team from Surrey has revealed that they can still survive the DNA replication mechanism inside cells and could potentially have health consequences. Quantum and classical effects in DNA point mutations: Watson–Crick tautomerism in AT and GC base pairs,(2021). This leads to these atoms occasionally being found on the wrong strand of DNA, leading to mutations. Proton tunneling involves the spontaneous disappearance of a proton from one location and the same proton’s re-appearance nearby.
