The problem of the origin of canonical and aberrant DNA mutations and the contribution of protons to genetic stability is an essential topic in molecular biology. Based on the empirical results, we reconsidered canonical and tautomeric mutations under the two-fluid model of quantum physics. We assumed that the pressure exerted by protons (H) in the DNA environment, through changes in pH, could alter the concentration ratio of canonical and tautomeric base pairs, which were found to be different at and beyond the criticality level, respectively. We anticipate that the deviation of the cellular system from a specific (critical) temperature at which dynamic entropy reaches a minimum and a critical pH occurs could result in tautomerization and point mutations.
标准和异常DNA突变的起源问题以及质子对遗传稳定性的影响是分子生物学中的一个重要课题。基于实验结果,我们在量子物理学的双流体模型下重新审视了标准突变和互变异构突变。我们假设,在DNA环境中,质子(H)通过改变pH值所施加的压力,可以改变标准碱基对和互变异构碱基对的浓度比,发现在临界水平及以上时它们是不同的。我们预计,细胞系统偏离动态熵达到最小值且发生临界pH值的特定(临界)温度,可能会导致互变异构化和点突变。
