Watch CRISPR edit genes in real time

For the first time, scientists can see CRISPR in action thanks to a real-time video published in Nature Communications. The movie shows what scientists had been able to infer from the indirect tools of biochemistry, and breaks down scene by scene how Cas9, CRISPR’s molecular scissors, cuts DNA, The Atlantic reports. The researchers say the visualization will further improve understanding of this revolutionary gene-editing technology.
