Association of the radiosensitivity and epigenetic pattern DNA changes at the conditions of prolonged irradiation was investigated. Two laboratory Drosophila melanogaster strains (Canton-s and ri) irradiated for 20 generations to low doses rate (1,2 · 10–8, 0,8 · 10–8 and 0,12 · 10–8 Gy/s) were used as experimental objects. DNA for the analysis was extracted separately for the flies of males and females. Restriction endonucleases GluI, GlaI were used. Restriction analysis has shown that there are different DNA methylated patterns for males and females as for control and exposed variants. At the chronic irradiation there was the decline of methylation level at the enzymes GluI, GlaI sites recognition.
