CRISPR/Cas9: Keep your friends close, but your viruses closer

"CRISPR", or clustered regularly interspaced short palindromic repeats, is an ancient bacterial mechanism that prevents the invasion of foreign pathogens to a host organism.  Specifically, the CRISPR sequence has been identified as a single DNA sequence that is repeated with unique sequences (found to be that of viruses) in-between.  Thus, bacteria have created an environment that allows them to recognize and attack viruses in case of a re-invasion.  "Cas", or CRISPR-associate protein, is the second part of this defense mechanism, and is responsible for cutting t
