Summary
Protons (H+) influence DNA stability by altering base pair concentrations via pH changes. Deviations from critical temperature and pH may lead to tautomerization and point mutations, impacting genetic stability.
Area of Science:
- Molecular Biology
- Quantum Physics
- Genetics
Background:
- The origin of DNA mutations and the role of protons in genetic stability are crucial in molecular biology.
- Understanding canonical and tautomeric mutations is essential for comprehending DNA integrity.
Purpose of the Study:
- To investigate the contribution of protons (H+) to DNA mutations and genetic stability.
- To re-examine canonical and tautomeric mutations using a quantum physics model.
Main Methods:
- Application of the two-fluid model of quantum physics.
- Analysis of proton pressure effects on DNA base pair ratios through pH variation.
Main Results:
- Proton pressure (H+) can alter the concentration ratio of canonical and tautomeric base pairs.
- These ratios differ significantly at and beyond a critical level.
Conclusions:
- Deviations from critical temperature and pH can induce tautomerization and point mutations.
- Proton concentration, influenced by pH, plays a key role in DNA mutation dynamics and genetic stability.

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

When an object is in equilibrium, it is either at rest or moving with a constant velocity. There are two types of equilibrium: static and dynamic. Static equilibrium occurs when an object is at rest, while dynamic equilibrium occurs when an object is moving with a constant velocity. In both cases, there must be a balance of forces acting on the object.
To understand the concept of equilibrium, let us first consider the forces acting on an object. When different forces act on an object, they can...

An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...

Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as...
