Main outcome of study (acc. to author)

Millimeter waves change the genome conformational state of E. coli cells. The resonance effect of millimeter waves manifests itself at power density up to 10-19 W/cm². The resonance effect on the genome conformational state at the early stationary phase changes the developmental dynamics of the exposed cells. The magnitude of the resonance millimeter wave effect depends on the concentration of irradiated cells.
