近几年，科学家们研究发现在南极的多数厚重冰层下潜藏着流动水，据此他们推断在水世界中潜藏着巨大的的微生物群体。

In recent years scientists have learned that liquid water lurks under much of Antarctica's massive ice sheet, and so, they say, the potential microbial habitat in this watery world is huge.

This is one of the biological properties, the naturally occurring properties of plasmids, is that they exist in microbial populations and they confer on them resistance from toxins that would ordinarily kill them.

这就是这类生物学特性之一,它是质粒所具有的自然特性,这些质粒存在于微生物群体中,并赋予微生物抗性,使它们免于被毒素杀死
