Despite the radiation completely shattering the Deionococcus’ DNA, the bacteria can repair the damage rapidly by “stitching its fragments back together” (DeWeerdt, 2002). Yet despite Deinococcus’ many extreme conditions, it does not thrive in these conditions, unlike extremophiles that categorize under “one” extreme condition (DeWeerdt, 2002). Their adaptability to various climates makes the bacteria hard to find a c0ncrete home for them; they are seen living in animal dung, sewers,
