2. Cas12a - Wikipedia

   en.wikipedia.org/wiki/Cas12a

   Like other Cas enzymes, Cas12a binds to a "guide" RNA (termed a crRNA, or CRISPR RNA) which targets it to a DNA sequence in a specific and programmable matter. In the host organism, the crRNA contains a constant region that is recognized by the Cas12a protein and a "spacer" region that is complementary to a piece of foreign nucleic acid (e.g. a ...

3. CRISPR activation - Wikipedia

   en.wikipedia.org/wiki/CRISPR_activation

   See: Guide RNA, CRISPR. Complementary base pairing between the sgRNA and genomic DNA allows targeting of Cas9 or dCas9. A small guide RNA (sgRNA), or gRNA is an RNA with around 20 nucleotides used to direct Cas9 or dCas9 to their targets. gRNAs contain two major regions of importance for CRISPR systems: the scaffold and spacer regions.

4. CRISPR RNA - Wikipedia

   en.wikipedia.org/wiki/CRISPR_RNA

   CRISPR RNA or crRNA is a RNA transcript from the CRISPR locus. [1] 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 .

5. CRISPR - Wikipedia

   en.wikipedia.org/wiki/CRISPR

   Cas9 (or "CRISPR-associated protein 9") is an enzyme that uses CRISPR sequences as a guide to recognize and open up specific strands of DNA that are complementary to the CRISPR sequence. Cas9 enzymes together with CRISPR sequences form the basis of a technology known as CRISPR-Cas9 that can be used to edit genes within living organisms.
