Short description
CRISPR-Cas9 is a genome editing tool that allows cutting DNA at the sequence of choice. It offers new opportunities for the therapy of viral diseases.
Detailed description
CRISPR-Cas is a kind of bacterial
immune system, which bacteria use to defend themselves against viruses. Scientists exploit CRISPR-Cas9 to switch off certain genes or to insert new genes at the cutting site. It is still controversial, whether CRISPR-Cas9 will routinely be used to treat human disease in the future.
