By flipping this field's polarity the DNA strand can be ratcheted along, one base pair at a time.

通过转动电场的极性，DNA链会渐进式地前进，一次一对碱基对。

Instead a single strand of DNA can be read, one base pair at a time, and without the need for labelling.

仅仅一条DNA链就可以被识读出来，一次一个碱基对，不需要带上标识。

So, in the case of neuroepithelial neoplasia, he said, they are looking for mutations outside of the 12 base pair segment of the gene.

因此，就神经上皮肿瘤而言，他们正在寻找此基因的12 bp片段以外的突变。

One of the things about these plasmids that makes them very useful is that their entire base pair sequences is known.

质粒之所以有用,其中一个原因就是,它的全部碱基序列都是已知的

It has to do with the nature of this complementary binding between double stranded DNA and the fidelity of this base pair matching in forming stable DNA molecules.

这些特性能从根本上解释,为何DNA双链的碱基能互补配对,以及在形成稳定的DNA分子结构时,碱基互补配对为何具有一致性

You know that messenger RNA is read in three base units called codons, and so this particular piece of messenger RNA is drawn in this cartoon in three base pair units.

RNA是按每三个碱基组成一个密码子,进行翻译的,在这幅动画中所画的mRNA,就是按三个碱基一组的方式来描绘的

However, typos do creep into the copy when the unnatural base pair is included.

ECONOMIST: A new kind of DNA

If and when these enzymes are perfected, the way will be open to make simple organisms engineered to carry the new base pair.

ECONOMIST: A new kind of DNA

Rather than inventing a new base pair, they have co-opted the least common of the three stop codons and used it to code for various new amino acids.
