It steers Cas9, the molecular scissors, to cut a precise portion of DNA.

它操纵分子剪刀Cas9，精确地切割DNA。

What it does then is it clips the casein—it's like a molecular scissors.

然后它把酪蛋白剪开——就像是一把分子剪刀。

Then it uses molecular scissors to snip through both strands, which switches off the faulty gene.

然后用分子剪刀将双链剪除，这样就可以阻止错误基因的表达。

Then you snip – or cut out – the mistake or faulty gene from the code using molecular scissors.

然后你可以用分子剪刀将异常基因剪除。

The best way of describing is the molecular scissors, so proteases are proteins that cut up other proteins.

对这种物质最好的形容就是分子剪刀，蛋白酶是切割其他蛋白质的蛋白质。

Cas9 is a DNA endonuclease, so that means it can cut DNA like a pair of molecular scissors.

Cas9是种DNA内切酶，这意味着它可以像把分子剪刀一样切断DNA。

Once bound, Cas9 acts like molecular scissors, cutting the DNA at the specified location.

一旦结合，Cas9 就像分子剪刀一样，在指定位置切割 DNA。

CRISPR-Cas9 acts like a pair of molecular scissors that cuts DNA at a precise location.

CRISPR-Cas9 就像一把分子剪刀，可以在精确的位置切割 DNA。

And the warhead in CRISPR is this purple protein that acts like molecular scissors to cut DNA, breaking the double helix into two pieces.

CRISPR中的弹头是一种紫色的蛋白质，就像分子剪刀一样切割DNA，将双螺旋断裂成两段。

A new frontier in genetics is CRISPR, a gene-editing tool that works like molecular scissors, enabling scientists to cut and paste fragments of DNA within cells.

CRISPR 是遗传学的一个新领域，它是一种基因编辑工具，工作原理就像分子剪刀，使科学家能够在细胞内剪切和粘贴 DNA 片段。

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。
