Abstract
The frequency of mutations in Bacillus subtilis spores irradiated anoxically with ionizing radiation decreased as a result of subsequent anoxic heating to the same extent as the increase in spore survival. This result indicates that DNA damage is the origin of the "thermorestoration" phenomenon.
摘要
在无氧条件下用电离辐射照射的枯草芽孢杆菌孢子中，突变频率因随后的无氧加热而降低，降低程度与孢子存活率的增加程度相同。这一结果表明，DNA损伤是“热修复”现象的起源。
