[DNA apurinization and apyrimidinization of gamma-irradiated silkworm embryos at different developmental stages].
A study was made of the formation and repair of apurine-apyrimidine (AP) sites in DNA of gamma-irradiated 3- and 7-day embryos of Bombyx mori differing drastically in radiosensitivity. The number of AP-sites in DNA immediately after irradiation was much larger in DNA of 3-day embryos than in DNA of 7-day embryos. The kinetics of the postirradiation recovery of AP sites in DNA of 3- and 7-day Bombyx mori embryos was heterogeneous and varied significantly.
