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。
Thus, any random changes in the interior, fledgling ribozymes that could speed up nucleic acid replication rates will spread rapidly through an evolving population.
它是一场梦在我们最亲密的进化亲属的脱氧核糖核酸上看看。
It was always a dream to look at the DNA of our closest evolutionary relatives.
一旦核酸-蛋白质操作系统形成，就不可能通过进化来“修补”成其他的系统，因为这种“修补”的后果会十分严重。
Once the nucleic acid-amino acid operating system came into existence it could never be "fixed" into anything else by evolution, because the immediate consequences would have been so serious.
植物核酸系统学的研究倍受青睐，因为核酸分子是最基本的进化单元，几乎不受主观因素影响。
The study of plant nucleic acid systematics has been followed with interest, because nucleic acid molecule is the most basic evolutional unit, it is not influenced by subjective factors.
在有文字记载的历史的这一万年间，在人的DNA中不存在由生物进化带来的可察觉的变化。(人的脱氧核糖核酸没有变化。)
There has been no detectable change in human DNA, brought about by biological evolution, in the ten thousand years of recorded history.
序列同源性分析表明，绵羊ttf - 1基因的核酸和蛋白质序列在不同哺乳动物之间有很高的同源性，分子在进化上均相当保守。
Homogeneous analysis demonstrated that nucleotide and amino acids sequences of sheep TTF-1 gene between different species mammal are comparatively conservative.
