Digital PCR, which quantifies individual pieces of target DNA, shows promise in further boosting accuracy.

量化单个目标 DNA 片段的数字 PCR 有望进一步提高准确性。

When these components are introduced into a cell, the Cas9 protein binds to the target DNA, guided by the RNA sequence.

当这些成分被引入细胞时，Cas9 蛋白在 RNA 序列的引导下与靶 DNA 结合。

We started by taking CRISPR scissors and disabling the ability to cut DNA while retaining its ability to search for and bind a target DNA sequence in a programmed manner.

我们从使用Crispr剪刀开始，禁用切割DNA的能力，同时保留以编程方式搜索和结合目标DNA序列的能力。

Here's how it works: The CRISPR system requires two key components – the Cas9 protein and a piece of RNA designed to match the target DNA sequence.

它的工作原理如下：CRISPR系统需要两个关键组件——Cas9蛋白和一段设计用于匹配目标DNA序列的RNA。
