nucleic

Organisms rely on phosphorus to build nucleic acids and other molecules to grow and proliferate.

有机物依赖于磷来制造核酸和其他生长与繁殖所需的分子。

Working with subsurface ice, brine or soil samples, SETG would attempt to isolate, amplify, detect and identify nucleic acids -- right there on Mars.

SETG研究了地下冰、盐水或土壤样本，试图隔离、放大、监测和识别核酸，这种核算恰好就在火星上。

Thus, any random changes in the interior, fledgling ribozymes that could speed up nucleic acid replication rates will spread rapidly through an evolving population.

这样一来，细胞内部发生的使得核酶加速核酸复制速率的任何变化，都会在进化群体中快速扩散。
