CRISPR-Cas13 is an RNA targeting and editing system based on the bacterial immune system that protects them from viruses. Cas13, previously known as C2c2, is the effector protein that targets and cleaves invading nucleic acids from viruses in type VI CRISPR-Cas systems. The CRISPR-Cas13 system is analogous to the CRISPR-Cas9 system. However, unlike Cas-9 which targets DNA, Cas-13 targets and cleaves single stranded RNA. Cas-13 was first discovered in L. shahii, a species of the Leptotrichia bacteria while researchers were looking for previously unidentified CRISPR systems. Members of Cas13, Cas13a and Cas13b are being developed for therapeutic gene correction at the RNA level and detection of viral pathogens.

- CRISPR/Cas ToolsClustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR associated (Cas) proteins perform adaptive immune functions in prokaryotic organisms defending against foreign nucleic acids such as viruses. CRISPR/Cas tools have been adapted for use in genome editing and other DNA and RNA targeting applications.

- RNARNA stands for ribonucleic acid. Messenger RNA (mRNA) is copied or transcribed from DNA and carries the coding information for the generation of a protein encoded by a gene. Different types of non-coding RNAs have roles in converting mRNA into protein and perform other regulatory functions in the cell.

- CRISPRClustered regularly interspaced short palindromic repeats (CRISPR) is a prokaryotic adaptive immune response that provides immunity against foreign nucleic acids, such as viral DNA and bacterial plasmids, through the use of crRNAs (CRISPR RNAs) and associated Cas genes.
