About the molecular signals

Abstract

A molecular signal is a molecule or an effect to which a cell responds by triggering a chain of intracellular events. A molecular signal is a special type of interaction between supramolecular systems, which include native proteins and DNA. Supramolecular chemistry describes this interaction as a molecular recognition reaction. This reaction occurs thanks to non covalent bonds, for example, hydrogen bonds, and there is not just one such bond, but many. The molecular recognition reaction can only occur between complementary supramolecular systems, and during the reaction, the structure undergoes deformation – its preorganization. A molecular signal can exist in a distant form – in the form of an effect on a supramolecular system of a group of entangled coherent photons emitted by another supramolecular system. There are known facts that allow us to interpret Gurvich’s ultra weak luminesce as a distant molecular signal. The effect of a molecular signal changes the tertiary and/or quaternary structure of DNA during preorganization, which may be the cause of mitogenetic effects. The molecular signal can and should be weak, since the energy barriers between different conformations of supramolecular systems are low. Fluctuations cannot drown out the molecular signal, since the information channel capacity of the multiple signal is non zero even under strong but local fluctuations. The distant molecular signal acts at distances of less than 1 cm. It has been experimentally proven that native DNAs have maximum susceptibility to molecular signals compared to denatured DNAs. These facts serve as a basis for the hypothesis that mitogenetic radiation is a distant molecular signal
