How does CRISPR work?

This is an educational video about CRISPR/Cas9 - a method for mutating, or knocking out, genes in a huge host of organisms, from mice to mosquitoes. CRISPR/Cas9 is a recent innovation in science that is revolutionizing the way we carry out our experiments and test hypotheses. By Tessa Montague, PhD student in Molecular Biology at Harvard University This video was created for high school students and teachers through the Derek Bok Center for Teaching and Learning at Harvard University. If you would like to try designing CRISPR guide RNAs yourself, you can visit our web tool, CHOPCHOP, which is used by scientists around the world: http://chopchop.cbu.uib.no/
