[Construction of an artificial digenic network with epigenetic properties].
A model of the simplest epigene was constructed to have two alternative states, which proved to be stable and transmittable through Escherichia coli cell generations. A switch from one to another state was induced by thermal and chemical external signals. The results gave further insight into the dynamic mechanism of preservation, coding, and transmission of the genetic information.
