The label on the nucleotide is not quite accurate .

核苷酸的称号不是很准确。

Their trouble with language had been caused by the change of a single nucleotide of dna-just one letter in the genetic sequence .

他们的语言问题仅仅是因为dna中一个核苷酸发生了改变，也就是说基因序列中有一个字母被改写了。

Replication of code sequences isn 't life , any more than replication of nucleotide sequences is , but we know that it sometimes leads to life .

代码序列的自我复制不是生命，也不比核苷酸序列更具生命性，但我们知道，它有时会导致生命的产生。

The breakthrough permits direct detection of each nucleotide , allowing an entire gene to be sequenced in about an hour .

这个重大的突破允许直接检测每个核苷酸，可以在大约一小时之内测序整个基因。

During rna editing , cells amend the nucleotide sequence of the rna , which can alter the sequence of amino acids in the resulting protein and change the protein 's function .

在rna编辑的过程中，细胞修饰了rna核苷酸序列，从而改变了后来蛋白质的氨基酸序列，再改变蛋白质功能。
