    從誘導過程之鐘形訊息亂度之時間趨勢表示正向反應變異為-阻抗能力之宿主菌確實已發生，因為再誘導菌相細胞之第二生長期並未發生因感染而失去細胞存活之現象。
  2. Exponential phase cultures of the dr rl strain survive exposure to gamma radiation at doses as high as 5, 000 gy without loss of viability or evidence of dna damage induced mutation. 6000 gy of irradiation will induce approximately 200 dna double - strand breaks in dr chromosomes, but it is still able to reconstruct a functional genome from chromosomal fragments without any mutation

    指數生長期的r1菌株即使在5kgy劑量的-射線照射后，其生長能力也未受影響， 6kgy -射線照射后染色體基因組產生約200個的雙鏈斷裂碎片，但是其基因組dna經修復后沒有引起任何的突變。
