Not only we can edit genetic code at will these days, for the first time we can actually see it being edited.

CRISPR is a powerful gene-editing tool that allows researchers to cut and paste snippets of DNA to make targeted changes to a living organism’s genome. It’s a method that’s fast and easy, and it has ushered in a new era of customized life.
Scientists have used the technique to breed mosquitoes that resistant to the malaria virus, develop treatments for muscular dystrophy, grow pig organssuitable for humans, cure blindness and invent new drugs—all this without ever actually seeing it in action.
But that all changed thanks to Japanese researcher Osamu Nureki, who, along with his colleagues, recorded video of CRISPR chopping a strand of DNA into two pieces. Nureki debuted the video in June before a crowd of scientists gathered for a conference in Big Sky, Montana. Scientists tend to mute their emotions when it comes to scrutinizing results in their field of study, but when Nureki hit play, gasps rippled through the crowd.
