Micrococcus radiodurans has been shown to sustain double-strand breaks in its DNA after exposure to X-radiation. Following sublethal doses of X-rays (200 krad in oxygen or less), the cells were able to repair these breaks, and an intermediate fast-sedimenting DNA component seemed to be involved in the repair process.
耐辐射微球菌经X射线照射后，其DNA能承受双链断裂。在亚致死剂量的X射线（在有氧或无氧条件下200千拉德）照射后，细胞能够修复这些断裂，并且一种快速沉降的DNA中间组分似乎参与了修复过程。
