This is the basis for the ORCH OR (orchestrated objective reduction) theory proposed by Roger Penrose and Stuart Hameroff.

After reading Penrose's book ^" the Emperor's New Mind", Stuart Hameroff (anesthesiologist) realized that his work with the brain's microtubules, might be the  biological "variable potentiometer" small enough to meet the requirements of quantum data (qubit) processing.

Their collaboration resulted in the birth of ORCH OR.

This may begin to delve into the depths of quantum consciousness.

Quantum and classical effects in DNA point mutations:

WatsonCrick tautomerism in AT and GC base pairs†

1 Introduction

Quote

Within the blueprint of life, spontaneous ‘spelling mistakes’ can occur, leading to potentially catastrophic errors. One possible candidate for these spontaneous mutations is the quantum mechanical tunnelling of hydrogen atoms within the bonds binding the DNA duplex together, or within the base 1,2. Hydrogen transfer in DNA bases leads to the creation of short-lived biologically relevant mutagens; referred to as tautomers. Keto-enol and amino-imino tautomerism are thought to be candidates for spontaneous mutation of DNA during replication and repair. In this work, the energy landscape of the canonical (standard, amino-keto) and tautomeric (non-standard, imino-enol) forms of the Adenine-Thymine (A-T) and Guanine-Cytosine (G-C) monomers and base pairs are modelled with the ab inito quantum mechanical approach of density functional theory (DFT). The reaction pathway of transfer can be modelled with transition state theory, providing an energy landscape of the process.
