Through the combination of CRISPRs and RNA - guided endonucleases, such as Cas9, («Cas» stands for CRISPR - associated), bacteria are able to utilize small customized crRNA molecules (for CRISPR RNA) to guide the targeting and degradation of matching DNA
sequences in invading viruses and plasmids to prevent them from replicating.
According to Siepel, this analysis will allow researchers to isolate functionally important
sequences in diseases much more rapidly.
