Abstract :
A DNA replication, mitosis, and binary fission hydrate hypothesis (MRH hypothesis) allowing non-trivial explanations for the physicochemical mechanisms of some intracellular processes is proposed. The hypothesis has a thermodynamic basis and is initiated by original experimental calorimetric and kinetic studies of the behavior of functional organic polymer and monomer substances in highly concentrated aqueous solutions. Experimental data demonstrating the occurrence of a short-range ordering in concentrated aqueous solutions of such substances are included. Hypothetical simple non-enzymatic unified mechanisms for the natural processes of DNA local unwinding preceding the start of duplication, DNA replication, formation and disappearance of the protein bonds between sister chromatids in the centromere region of eukaryotic DNA and in the centromere-like region of prokaryotic DNA, moving of daughter chromosomes apart to the opposite sides of cells in late anaphase, and formation of the nuclear envelopes in telophase and intracellular membranes between the newly formed nuclei in cytokinesis are formulated. The nature of a number of other intracellular phenomena is discussed.
