Proton tunneling leads to spontaneous mutations within DNA and cancer

Quantum biology is a new field of science founded in the 1920s that studies whether a subatomic

the world of quantum mechanics role in living cells. Quantum mechanics is by its very nature an interdisciplinary field that brings together nuclear physicists, biochemists, and molecular biologists.

“Many have long suspected that the quantum worldweird, illogical and wonderful, and it plays a role in the body. But part of our body can be present in two places at the same time, because in the quantum world it happens all the time, and our research confirms that quantum tunneling also occurs in DNA at room temperature.

Proton tunneling involves spontaneousthe disappearance of a proton from one place and the reappearance of the same proton nearby. The research team found that very light hydrogen atoms provide bonds that hold the two strands of the DNA double helix together. But they can, under certain conditions, behave like propagating waves that can exist in several places simultaneously due to proton tunneling. This leads to the fact that these atoms are sometimes found on the wrong DNA strand, which leads to mutations. short-lived but biologically significant point mutations, which can further lead to gene mutations and possibly cancer.

Scientist team shows mutations can survivein the mechanism of DNA replication within cells and potentially cause health problems. They are short-lived, but they are biologically significant, albeit pinpoint, which can further lead to mutation of an entire gene and, possibly, to cancer. This is because the quantum mechanical tunneling of hydrogen atoms occurs inside the bonds that link the DNA duplex together, in other words, inside the DNA base.
