X射线在小鼠白血病细胞、耐辐射微球菌和分离的DNA中产生的DNA多核苷酸链断裂数大致相同。白血病细胞有一个有效的系统来重新连接断裂的链。结果还表明，哺乳动物DNA的分子量很高。
The number of breaks produced by X-rays In the polynucleotide chains of the DNA in murine leukaemia cells, the bacterium Micrococcus radiodurans and in Isolated DNA are approximately the same. The leukaemia cells have an efficient system for rejoining broken strands. The results also suggest that the molecular weight of the mammalian DNA is very high.
