The CRISPR/Cas system works by snipping short DNA elements from the genomes of infecting viruses, integrating those elements into the bacterium’s genome (at the CRISPR locus), and using the RNAs ...

CRISPR-Cas systems have a remarkable capability to form immunological memories by integrating short segments of invading genomes, called “spacers” into the CRISPR locus in the genome of the bacterial ...
