That's what scientists have made using a new technique for building super-tiny shapes using the familiar double helix of DNA.

这就是科学家们使用一种DNA新技术创造出来的神奇景象，这种技术使用DNA的双重螺旋来构造超微小的材料。

From a distance, these building blocks look very similar, so every piece of DNA you look at has the same overall shape—the famous Watson-Crick Double Helix.

从远处看，这些基本成分看上去极为相似，因此 DNA 的每一部分的基本形状都是相同的 — 著名的沃森克里克双螺旋结构。

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。

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

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

It was as though their privation was somehow genetic, transferred biologically in some sad double helix of DNA from one Zulu generation to the next.

The double helix nature of DNA may have come to Watson divergently in a dream, but it was preceded by years of convergent thinking.

FORBES: The Pittsburgh Six: The Template for Innovation

This is demonstrated in the exhibition's giant model of a City Hall Tower for Philadelphia that was never built, a dramatic double helix derived from the discovery of DNA in 1953.
