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。

Structurally, DNA is composed of two strands that intertwine to form a spring-like structure called the double helix.

从结构上讲，DNA是由两条链相互缠绕构成弹簧状结构称为双螺旋。

Whether we really understand DNA is debatable, but Francis Crick and James D. Watson published the first of many papers describing the double helix structure on this day in 1953.

我们是否真正了解了DNA仍值得商榷，但1953年的这一天，弗朗西斯·克里克(Francis Crick)和詹姆斯·d·沃森发表了系列论文的第一篇，阐述了DNA的双螺旋结构。

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 DNA is a double helix and I've only shown you one part of the helix, right? I've shown you one upright strut and a base hanging off of it, but it forms a double helix because complementary strands of DNA strongly associate with one another and that's a very stable structure.

NA是双螺旋,我只是给你们讲了螺旋的一边,我给你们演示,一条链的支柱及碱基团,但其能构成双螺旋,是因为DNA是完全互补的两条链,彼此之间结合紧密,结构异常稳定

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