WebCRISPR/Cas systems provide bacteria and archaea with small RNA-based adaptive immunity against foreign elements such as phages and plasmids. An important step in the resistance mechanism involves the generation of small guide RNAs (crRNAs) that, in combination with Cas proteins, recognize and inhibit foreign nucleic acids in a sequence …
