You'll be familiar with the double helix of DNA.

您会熟悉 DNA 双螺旋结构。

Well, just a little thing called the double helix structure of DNA.

好吧， 只是一个叫做 DNA 双螺旋结构的小​​东西。

CRISPR-Cas9 nickases, for example, are enzymes that cut only one strand of the DNA double helix.

例如，CRISPR-Cas9 切口酶是仅切割 DNA 双螺旋一条链的酶。

In 1953, it was Watson and Crick who described the structure of DNA as a double helix.

1953 年，沃森和克里克将 DNA 结构描述为双螺旋结构。

This double helix structure carries the instructions for making all the proteins a cell will ever need.

这种双螺旋结构携带着制造细胞所需的所有蛋白质的指令。

To make that iconic double helix structure, the bases of one strand pair up with the bases of another strand.

为了形成标志性的双螺旋结构， 一条链的碱基与另一条链的碱基配对。

One way to visualize how this happens is to take a double helix and see how the two halves of the helix come apart right here in the middle.

将这一过程可视化的一种方法是拿一个双螺旋，看看螺旋的两半是如何在中间分开的。

The now-famous double helix is almost synonymous with Watson and Crick, two of the scientists who won the Nobel Prize for figuring it out.

现在著名的双螺旋结构几乎与华生和克里克同义，这两位科学家因发现双螺旋结构而获得诺贝尔奖。

Your DNA is made up of two strains that wrap around each other in the famous double helix structure, to get even more compact and tiny, that DNA is wrapped around little proteins called histones.

你的DNA是由两个菌株组成的，它们以著名的双螺旋结构相互缠绕，变得更加紧密和微小，DNA被包裹在称为组蛋白的小蛋白质上。

You may have heard that her data supported Watson and Crick's brilliant idea, or that she was a plain-dressing, belligerent scientist, which is how Watson actually described her in " The Double Helix."

你可能听说过她的数据支持沃森和克里克的绝妙想法，或者她是一位穿着朴素、好战的科学家，这就是沃森在“双螺旋” 中对她的真实描述。

That defense mechanism is now better known as CRISPR. And the warhead in CRISPR is this purple protein that acts like molecular scissors to cut DNA, breaking the double helix into two pieces.

这种防御机制现在被称为 CRISPR。 CRISPR 中的弹头是这种紫色蛋白质，它像分子剪刀一样剪断 DNA，将双螺旋结构分成两部分。
