double-helix

基本解释

The structures are made from bundles of double-helix DNA strands.
这些结构是由一束束双螺旋DNA链构成。
He'd also provided Watson, without Franklin's knowledge, with her key photograph, which showed -- for the first time -- the double-helix shape that underlies the structure of DNA.
他并且背着弗兰克林，把她拍摄的关键照片提供给沃森，这张照片表明——第一次表明——构成DNA结构的是双螺旋状态。
From the surface it looks like nothing more exciting than a stationary grey barge; but below are two spinning turbines, known as foils, which look like a whirling carbon-fibre double-helix.
从表面上看它顶多像个固定的灰色拖船；但在底下有两台旋转涡轮机，外号薄片，看起来像一个旋转的碳纤维双螺旋体。

Hybridization simply means that DNA will re-nature and form a stable double helix only with its particular match, only with the hybrid that it is perfectly complementary, too.
核酸分子杂交表示,DNA在变性状态下可以恢复活性,和与其配对的单链形成稳定的双螺旋结构,只有在完全配对时才会发生这种情况

DNA is a double helix, you know this, the double helix was--the structure of DNA was discovered about the time that I was born you've always lived with it.
NA是双螺旋结构,众所周知,DNA的这种双螺旋结构,是在我出生的那个年代才被发现的,它就是你生命的一部分

Now remember that there were only four different colors in the cartoon of the DNA double helix that we talked about and I told you that those colors are really - represent the bases but there's five of them here.
现在要记住只有四种不同的颜色,在双螺旋DNA的卡通模型上出现,我们刚说过这个,我告诉你们的这些颜色,它们代表不同的碱基,不过有五种碱基

Antisense drugs are named after one of DNA's two strands in its double-helix structure, which are known as sense and antisense.
FORBES: Antisense and Sensibility

the form of the molecular structure of DNA, consisting of two helical polynucleotide chains linked by hydrogen bonds and coiled around the same axis DNA

双螺旋
Base excision repair is to excise and restore bases so thatgenetic protein could restore normal DNA double-helix structure, thus it prevents genetic mutation and keeps the genetic stability.
碱基切除修复是通过切除修复碱基,使基因重新恢复正常的DNA双螺旋结构,从而防止基因突变,维持遗传稳定性。
