Abstract excerpt
The CRISPR-Cas system owes its utility as a genome-editing tool to its origin as a prokaryotic immune system. The first demonstration of its activity against bacterial viruses (phages) is also the first record of phages evading that immunity 1 . This evasion can be due to point mutations 1 , large-scale deletions 2 , DNA modifications 3 , or phage-encoded proteins that interfere with the CRISPR-Cas system, known...
