A specific sequence of guide RNA could be made to attach to a spot virtually anywhere on the genome, and the Cas9 protein would cleave the DNA at that spot. Then pieces of the DNA could be deleted or added, just as a film editor might cut a film and splice in new frames.

  • Cas9蛋白系统中一个特定的向导RNA序列可附着在基因组上几乎任何一个位置,Cas9蛋白会切开DNA序列的特定位点,然后在这个位点添加或删除特定的DNA片段,如同电影剪辑那样,删掉或拼接上一个新的电影片段。
