A study published in the international journal Journal of Theoretical Biology modeled that when type II endonucleases cleave DNA double strands, the perfectly simultaneous cleavage between the two catalytic centers is synchronized by quantum entanglement. It elucidated that the restriction enzyme pushes away water molecules around the DNA recognition sequence to form a decoherence shield, thereby safely preserving the quantum state even amidst physiological thermal noise. It is disruptive evidence proving the exquisite operating principle of life's gene scissors through a quantum entanglement mechanism that transcends spatial separation, with zero-point modes of coherent oscillation providing the cleavage energy. [Quantum Biology Society] Restriction enzymes, which precisely locate and cut specific sites on DNA double strands, are among the most important tools underpinning modern biotechnology. Among them, how the most widely used type II endonucleases simultaneously break the phosphodiester bonds of both DNA strands without a single margin of error has long remained a puzzle in the biological community. This is because the macroscopic 3D structural changes of proteins alone were insufficient to explain such a perfectly timed simultaneous cleavage mechanism. The study "How quantum entanglement in DNA synchronizes double-strand breakage by type II restriction endonucleases," recently published in the international journal Journal of Theoretical Biology, revealed that the secret to this phenomenal synchronization lies in quantum entanglement, the most bizarre phenomenon in physics. A research team including Professor P. Kurian, G. Dunston, and J. Lindesay from Howard University in the US spearheaded this innovative study. ■ A Quantum Shield Created by Pushing Away Water Molecules The research team approached the enzyme catalysis reaction by quantum mechanically modeling the collective behavior of electrons present inside the DNA helix. When a restriction enzyme binds to a specific recognition sequence (palindromic structure) of the target DNA, the enzyme imposes physical boundary conditions and simultaneously pushes the water molecules around the binding site outward. The research team explained that this exclusion process goes beyond simple binding and acts as a decoherence shield that prevents the collapse of microscopic quantum states from the hot, complex thermal noise inside the body. Within this protein shield, dipole-dipole oscillations inside the DNA can be fully quantized without disturbance. ■ Simultaneous Cleavage Induced by Entanglement Transcending Space The zero-point modes of coherent oscillation safely formed in this way supply the crucial energy required for the enzyme to break the robust phosphodiester chemical bonds. In particular, the unique palindromic mirror symmetry harbored by the enzyme-DNA binding complex perfectly preserves quantum mechanical parity. As a result, a continuous correlation is formed between the two physically distant catalytic centers, binding them like a single quantum system. In other words, through the state of quantum entanglement, the cleavage of one strand and the cleavage of the opposite strand are synchronized in real-time, transcending space. This study is evaluated as a monumental achievement showing that the genetic manipulation and repair processes of macroscopic living organisms are actually governed by an extremely exquisitely controlled quantum entanglement network. #QuantumEntanglement #GeneScissors #RestrictionEnzymes #DNADoubleStrandBreakage #Synchronization #QuantumBiology #GeneEditing #Biophysics #QuantumInformation #KoreanSocietyOfQuantumBiology https://pmc.ncbi.nlm.nih.gov/articles/PMC4746125/

Several living systems have been examined for their apparent optimization of structure and function for quantum behavior at biological length scales. Orthodox type II endonucleases, the largest class of restriction enzymes, recognize four-to-eight base pair sequences of palindromic DNA, cut both strands symmetrically, and act without an external metabolite such as ATP. While it is known that these enzymes induce strand breaks by attacking phosphodiester bonds, what remains unclear is the mechanism by which cutting occurs in concert at the catalytic centers. Previous studies indicate the primacy of intimate DNA contacts made by the specifically bound enzyme in coordinating the two synchronized cuts. We propose that collective electronic behavior in the DNA helix generates coherent oscillations, quantized through boundary conditions imposed by the endonuclease, that provide the energy required to break two phosphodiester bonds. Such quanta may be preserved in the presence of thermal noise and electromagnetic interference through decoherence shielding, the specific complex's exclusion of water and ions surrounding the helix. Clamping energy imparted by the enzyme decoherence shield is comparable with zero-point modes of the dipole-dipole oscillations in the DNA recognition sequence. The palindromic mirror symmetry of this sequence should conserve parity during the process. Experimental data corroborate that symmetric bond-breaking ceases when the symmetry of the endonuclease complex is violated, or when environmental parameters are perturbed far from biological optima. Persistent correlation between states in DNA sequence across spatial separations of any length--a characteristic signature of quantum entanglement--may be explained by such a physical mechanism.
A study published on arXiv proved through a mathematical model that the macroscopic electron clouds shared between adjacent base pairs inside the DNA double helix structure maintain a strong quantum entanglement state even at room temperature (300 K), which is around body temperature. As a result of modeling the electron clouds of the DNA molecule as a chain of coupled quantum harmonic oscillators, it was confirmed that the van der Waals binding energy due to the dipole-dipole interaction between adjacent bases matches the pure quantum entanglement energy. This is a revolutionary study showing that the inherent structural stability of DNA, which is difficult to fully explain with classical physics or thermodynamics alone, is fundamentally protected by the quantum superposition and entanglement of electrons, suggesting that the genetic information preservation system of living organisms is an optimized quantum system capable of withstanding thermal noise. [Quantum Biology Society] How DNA, the most fundamental genetic information preservation system of life, can maintain such perfect structural stability even in a complex and unstable biological environment has long been a massive mystery in the biological community. Until now, it has been thought that classical thermodynamic hydrogen bonds and van der Waals forces between base pairs maintain this stability. Recently, however, a groundbreaking study mathematically proving that the source of microscopic interactions occurring inside DNA is none other than quantum entanglement has been published, drawing the attention of the global scientific community. The paper titled "Quantum entanglement between the electron clouds of nucleic acids in DNA," published in the preprint repository arXiv, is a monumental achievement conducted by a joint research team including Elisabeth Rieper and Vlatko Vedral of the Centre for Quantum Technologies (CQT) at the National University of Singapore, and Janet Anders of University College London (UCL) in the UK. ■ Quantum Entanglement of DNA Electron Clouds Maintained at Room Temperature The research team modeled the electron clouds of a single DNA strand as a chain of coupled quantum harmonic oscillators with dipole-dipole interaction between nearest neighbors. By mathematically analyzing the behavior of the macroscopic electron clouds shared between adjacent base pairs, the researchers theoretically proved that the coupling between electron clouds is dominant over the biological temperature (300 K), indicating that a very strong nearest neighbor entanglement state exists without being destroyed even in a room temperature environment. The simulator below helps to intuitively understand how the electron clouds between adjacent DNA bases form quantum entanglement and how that coupling (entanglement) changes depending on the distance and interaction strength between bases. ■ A Quantum Mechanical Shield Protecting the Genetic Information of Life This study clearly shows the surprising fact that the van der Waals binding energy connecting the DNA strands is practically identical to the binding energy of the coupled chain derived from the quantum entanglement of electrons. Contrary to the conventional wisdom that quantum states are easily destroyed in a hot and wet biological environment, DNA was instead effectively withstanding macroscopic thermal noise and defending against errors in genetic information by strongly entangling the electron clouds of neighboring bases. This strongly suggests that the genetic material of life itself operates as a highly optimized quantum system through a long evolutionary process, presenting a new milestone in the convergence research of modern quantum biology and genetics. https://arxiv.org/abs/1006.4053
• A study published in the international journal Communications Physics demonstrated the phenomenon of proton tunneling inside DNA utilizing an open quantum systems approach. • The research confirmed that protons within DNA hydrogen bonds pass through binding barriers via quantum tunnelling, going well beyond simple thermal fluctuations, and that this plays a dominant role in the conversion of base pairs into rare tautomers. • This is a groundbreaking result proving that the fundamental genetic mutation process of life is driven by microscopic quantum tunneling probabilities, revealing that tautomeric states can induce natural point mutations. [Quantum Biology Society] The DNA double helix, which contains all the genetic information of living organisms, is stably maintained by hydrogen bonds between base pairs. However, even in this robust structure, unexplained point mutations occasionally occur, becoming the seeds of evolution and disease. Recently, a study demonstrating that quantum tunnelling—a bizarre physical law of the subatomic world—is deeply involved behind this fundamental biological phenomenon was published, surprising both the biology and physics communities. The paper detailing this groundbreaking discovery, titled "An open quantum systems approach to proton tunnelling in DNA," was made freely available in Communications Physics, a sister journal to the world-renowned Nature. A research team consisting of Louie Slocombe, Marco Sacchi, and Jim Al-Khalili from the University of Surrey in the UK led this interdisciplinary study. ■ The Power of Quantum Tunneling Beyond Classical Chemistry From the perspective of general classical biochemistry, it has been assumed that for protons forming DNA hydrogen bonds to change positions, sufficient thermal fluctuation is required to overcome the binding barrier. However, the researchers discovered a surprising fact through an open quantum systems model that precisely reflects the effects of decoherence and dissipation within the cellular environment. Protons instantly change their binding positions through quantum tunneling, passing through the barrier despite a lack of energy, and the contribution of quantum tunneling to the chemical reaction rate is several orders of magnitude larger than classical over-the-barrier hopping. ■ The Beginning of Mutation: Tautomeric Conversion According to the analysis, this quantum tunneling plays a dominant role in the conversion of Guanine-Cytosine (G-C) base pairs from their canonical form into highly rare and unstable tautomeric forms. The problem arises when the DNA strands are separated by the helicase enzyme and replication occurs in this state. The research team confirmed that at biological temperatures (around 300K), the thermal equilibrium occupation probability of the tautomer reaches an astoundingly high value of 1.73 × 10⁻⁴. This is significantly higher than the previously known natural spontaneous mutation rate (about 10⁻⁸), strongly suggesting that tautomerisation via quantum tunneling is a substantial and crucial cause of point mutations. ■ Presenting a New Paradigm in Life Sciences This study is a monumental achievement proving that genetic stability and the mutation process—the most fundamental and secretive domain of life—are not accidental chemical mistakes but are directly driven by the probability of quantum tunneling, a physical law of the microscopic world. This is a powerful demonstration that overturns the conventional view of interpreting biological phenomena solely through macroscopic molecular structures and chemical bonds, showing that quantum mechanics can be the key to fully explaining genetic mutation models.
A study published on arXiv has strictly demonstrated the existence of true multipartite quantum entanglement between bacteriochlorophyll-a (BChl a) molecules within the Fenna-Matthews-Olson (FMO) light-harvesting complex of green sulfur bacteria. Using entanglement measures in the single-excitation subspace (bipartite concurrence and a global entanglement measure), the study proved for the first time in a biological system that these entanglement states persist for approximately 2 picoseconds (ps) not only at cryogenic temperatures but also at physiological temperatures (300 K, room temperature), surviving macroscopically. The findings suggest that strong quantum entanglement between distant molecules can enhance the robustness and efficiency of the energy transfer network as the exciton moves toward the reaction center, even amidst environmental noise (decohering effects). [Quantum Biology Society] Photosynthesis, known as one of the most efficient energy conversion processes in nature, has long been a subject of wonder for scientists. While previous research focused on quantum coherence at the single-particle level, a groundbreaking study has recently been published mathematically proving that "true quantum entanglement"—the non-local correlation between multiple pigment molecules—actually operates within living organisms, drawing global attention. The paper titled "Quantum entanglement in photosynthetic light harvesting complexes," published in the preprint repository arXiv, is evaluated as a monumental achievement in elucidating macroscopic quantum phenomena in biological systems. An international joint research team led by Mohan Sarovar, Akihito Ishizaki, Graham R. Fleming, and K. Birgitta Whaley from UC Berkeley and Lawrence Berkeley National Laboratory (LBNL) in the USA spearheaded this innovative research. ■ Demonstration of Multipartite Quantum Entanglement within the FMO Complex The researchers focused on the FMO (Fenna-Matthews-Olson) light-harvesting complex of green sulfur bacteria (Chlorobium tepidum). By precisely analyzing the exciton dynamics between the pigment molecules within the complex using a non-Markovian quantum master equation, they proved through bipartite concurrence and a measure of global entanglement that true multipartite quantum entanglement is formed, going beyond simple individual coherence. This marks the first rigorous instance of quantifying quantum entanglement in a biological system. ■ Quantum Information Maintained Through Room-Temperature Noise The most surprising discovery is that these delicate quantum entanglement states survive meaningfully even at warm and wet physiological temperatures. While it was generally thought that quantum states are instantly destroyed by the thermal fluctuations of the surrounding proteins and solvent (decohering effects), the study's results confirmed that the natural FMO complex maintains bipartite entanglement between dimerized pigments and even a small amount of long-range and multipartite entanglement at 300 K. This entanglement plays a crucial role in enhancing the efficiency and robustness of the energy transfer network as the exciton travels to the reaction center. ■ Living Organisms as Optimized Quantum Machines This study suggests that living organisms are not merely losing quantum phenomena in harsh environmental noise but are rather highly designed, optimized quantum machines that endure and actively utilize them. Mimicking these perfect energy transfer mechanisms of nature is expected to provide key physical clues for maximizing the efficiency of next-generation solar cells or developing innovative quantum communication and metrology devices that operate robustly even at room temperature. https://arxiv.org/abs/0905.3787
A study published on bioRxiv demonstrated that quantum tunneling plays a key role in in vitro hydrolytic enzyme reactions by analyzing kinetic isotope effects (KIE) through deuterium substitution. The involvement of the quantum tunneling effect was confirmed through temperature dependence experiments in major biochemical reactions such as SIRT3-mediated deacetylation, I-SceI-mediated DNA cleavage, and caspase-3-mediated protein cleavage. By observing that DNA homologous recombinational (HR) repair in living cells is almost completely inhibited in a deuterium environment that lowers the probability of quantum tunneling, it was demonstrated that quantum effects dominate cell survival itself. [Quantum Biology Society] Behind life phenomena lies a strange quantum world that cannot be explained by classical mechanics. A prime example is quantum tunneling, where particles pass through reaction energy barriers as if by magic. While it has been known that quantum tunneling contributes to speeding up some enzyme reactions inside proteins , there has been a lack of concrete empirical evidence as to whether this is an essential physical requirement directly linked to actual cell survival. Recently, a groundbreaking study was published showing that if the quantum tunneling effect is inhibited, the cell's life support system itself completely halts. The paper titled "Cell viability is dominated by quantum effects," published on the preprint repository bioRxiv, strongly supports this. A multi-institutional joint research team, including Takeshi Yasuda from the National Institutes for Quantum and Radiological Sciences and Technology (QST) and Kobe University in Japan, led this innovative research. ■ The Link Between Enzyme Hydrolysis and Quantum Tunneling The research team utilized deuterium, an isotope of hydrogen, to track how quantum tunneling is involved in enzymatic chemical reactions. In a heavy deuterium environment, the probability of quantum tunneling is significantly lower compared to light hydrogen, and the research team precisely measured the resulting kinetic isotope effects (KIE) and their temperature dependence. Experimental results proved that the quantum tunneling effect is deeply involved in in vitro hydrolysis reactions essential for cellular metabolism, such as SIRT3-mediated deacetylation, I-SceI-mediated DNA cleavage, and caspase-3-mediated protein cleavage, as evidenced by the disappearance of the isotope effect above specific temperatures. ■ A Halted DNA Repair System Furthermore, the research team directly investigated the impact of the quantum characteristics of these enzyme reactions on living cells. When human cells were exposed to a deuterium-substituted (D₂O) medium environment that artificially lowered the probability of quantum tunneling, it was observed that DNA homologous recombinational (HR) repair, one of the core survival mechanisms of cells, was almost completely inhibited. This means that the most important biochemical repair process protecting and maintaining the genetic information of organisms undergoes a chain reaction of several enzymes and cannot function normally without quantum tunneling phenomena. ■ Quantum Effects Dominating Cell Viability This study empirically demonstrates that core biochemical reactions in living organisms do not simply rely on thermodynamic energy but are fundamentally indebted to quantum mechanical tunneling phenomena. The discovery that numerous hydrolysis and repair reactions performed by enzymes within cells are ultimately strictly dominated by quantum effects serves as crucial evidence that rewrites life phenomena from a purely quantum physics perspective. https://www.biorxiv.org/content/10.1101/2023.07.18.549596v1
