Can anyone throw some light on CRISPR

For explanation will give brainliest :)

In a series of experiments using human cancer cell lines, scientists at Johns Hopkins Medicine say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel known as CRISPR, and observe how specialized cell proteins repair the exact spot where the gene was cut.

Results of the experiments, published June 11 in Science, not only reveal new details about the DNA repair process, but also are likely, the researchers say, to speed up and aid understanding of the DNA activity that typically causes aging and many cancers.

≅200-130 milions years ago pangea splited in 2 continents

the index of refraction of the second medium is higher. i just took the test trust me !
