Abstract

At the considerable enzyme's abundance the accessibility some rat thymus DNA sites, for EcoRI-restriction varies depending on the interval after a single γ-irradiation in vivo. At a first hours for 5 Gy the sign-opposite effects for the fragments 1500 and 345 b. p. are occured-increasing and decreasing of the relative portions accordingly – with the returning to initial restriction level to 24-th hour. The doze 0,5 Gy causes a similar genome's reaction in terms of restriction accessibility, but the manifestation occured only in a day.
