Resonance Effect of Microwaves on the Genome Conformational State of E. coli Cells

Abstract

The effect of low intensity microwaves on the conformational state of the genome of X-irradiated E. coli cells was studied by the method of viscosity anomalous tim dependencies.It has been established that within the ranges of 51.62-51.84 GHz and 41.25-41.50 GHz thefrequency dependence of the observed effect has a resonance nature with a resonance halfwidthof the order of 100 MHz. The power dependence of the microwave effect within therange of 0.1 -2 0 0 (iW/cm2 has shown that a power density of 1 nW/cm2 is sufficient to suppress radiation-induced repair of the genome conformational state.The effect of microwave suppressionof repair is well reproduced and does not depend on the sequence of cell exposure toX-rays and microwave radiation in the millimeter band.The results obtained indicate the roleof the cell genome in the resonant interactionof cells with low intensity millimeter waves. © 1992, Walter de Gruyter.
