The sensitivity of Drosophila eggs to the lethal action of X-rays does not remain constant during embryogenesis. The X-ray doses used in the present investigation may retard the hatching of the larvae but do not block development immediately after irradiation. A fraction of the damage induced in young embryos is repaired during gastrulation. The amount of repair is independent of the X-ray dose but is influenced by the temperature. The damage can be repaired even after the cells of the embryo have undergone many mitotic cycles.
果蝇卵对X射线致死作用的敏感性在胚胎发育过程中并非保持恒定。本研究中使用的X射线剂量可能会延迟幼虫孵化,但不会在照射后立即阻止发育。在原肠胚形成过程中,年轻胚胎中诱导的一部分损伤会得到修复。修复量与X射线剂量无关,但受温度影响。即使胚胎细胞经历了许多有丝分裂周期,损伤仍可得到修复。
