Bacillus megateriunm spores labeled with tritiated thymidine were irradiated with monochromatic ultraviolet light, and the DNA of the spores was analvzed for thymine-containing, products. No thymine dimers were observed, but three other thymine photoproducts were found. The unknown products of radiation were produced in vitro by irradiation of DNA that had been dried in the, presence of various salts.
用氚标记的巨大芽孢杆菌孢子进行单色紫外线照射，并分析孢子的 DNA 中含胸腺嘧啶的产物。未观察到胸腺嘧啶二聚体，但发现了另外三种胸腺嘧啶光产物。在存在各种盐的情况下干燥 DNA 并进行体外照射，产生了辐射的未知产物。
