The staples bring two distant parts of the DNA strand together so that it folds.

这些短链dna将长链dna的两端缠在一起，这样长链dna就折叠起来了。

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。

This also involves a nanopore in an AHL protein, but the DNA strand does not pass through the nanopore intact.

这也需要在AHL蛋白质上有个孔道，但是DNA链不再原原本本地穿过纳米孔。

So DNA is replicated using one strand of the DNA as a template.

所以DNA复制是以DNA单链为模板的

We call it the complement and each strand of DNA, each polymer of DNA that you could make or you could draw has only one complement and that complement has the following features.

我们称之为互补链,每个DNA聚合物,都只有一种互补链,互补链有以下特点

Well, what if you knew the sequence for the messenger RNA that made insulin and you designed another single stranded DNA or RNA molecule that was the exact opposite, or the exact compliment, I should say, of that strand?

那么,如果你知道了,合成胰岛素的mRNA的序列,并设计一段与其序列完全相反的,DNA或者RNA分子,应该说是完全互补的一段分子

The machine takes a single DNA strand and uses an enzyme to attach bases to it.

The harder part will be designing a detector that can distinguish between two adjacent letters on a DNA strand, which are half a nanometer apart, a small fraction of the wavelength of light.

Transcriptors substitute DNA for semiconductors and RNA for the electrons in traditional transistors -- essentially, the transcriptor controls the flow of a specific RNA protein along a DNA strand using tailored combinations of enzymes.
