"Well, what are the essential parts of this little machine?"
00:00:07.267 --> 00:00:10.226
In nature, what CRISPR systems are doing is,
00:00:10.027 --> 00:00:12.881
they're giving bacteria immunity to viruses,
00:00:12.925 --> 00:00:14.883
so they're protecting them from viruses.

Movie Summary

A breakthrough called CRISPR opens the door to curing diseases, reshaping the biosphere, and designing our own children. A provocative exploration of its far-reaching implications, through the eyes of the scientists who discovered it
