The number of genome equivalents of DNA per cell of M. radiodurans changed from approximately 5 to 10 depending on the media used. The sensitivity to ultraviolet light or gamma-rays was not different between the cells with different genome multiplicity. This suggests that the efficient repair process for DNA damage expressed in M. radiodurans is not influenced by the multiplicity of genomes in a cell.
耐辐射球菌每个细胞的DNA基因组当量数根据所用培养基的不同，从大约5变化到10。不同基因组倍数的细胞对紫外线或伽马射线的敏感性并无差异。这表明耐辐射球菌中所表现出的针对DNA损伤的高效修复过程不受细胞中基因组倍数的影响。
