CRISPR RNA or crRNA is a RNA transcript from the CRISPR locus. CRISPR-Cas (clustered, regularly interspaced short palindromic repeats - CRISPR associated systems) is an adaptive immune system found in bacteria and archaea to protect against mobile genetic elements, like viruses, plasmids, and transposons. The CRISPR locus contains a series of repeats interspaced with unique spacers. Th… WebOther CRISPR systems, specifically the Type VI CRISPR enzymes Cas13a/C2c2 and Cas13b, target RNA rather than DNA.

To edit a genome using the CRISPR-Cas9 genetic scissors, first the DNA sequence is identified that is to be edited. Once identified, a single guide RNA (sgRNA) is designed to find and bind to the specific sequence in the DNA. The guide RNA has a sequence that is complementary to those of the target DNA.
