Especially, hyperthermophilic archaea can flourish in habitats of extreme temperatures, without obvious difference in genetic mutation frequency from organisms living in mesophilic environments. This fact indicates the existence of a unique and effective DNA repair system in thermophilic archaea.
值得注意的是超嗜热古菌比起一般生物生活环境更加恶劣,但是仍然能活跃生存在那种极端环境中,其体内必定含有更优越的DNA损伤修复机制。
