This new technique uses CRISPR-Cas3, while most of the work we've seen so far has been made with CRISPR-Cas9. The tool uses a complex of riboprotein, known as Cascade, to seek its purpose, and an enzyme called Cas3 to tear the DNA. As a result, it can move along the DNA of dozens of kilobases long and break the genetic material as it goes. This may be particularly useful for understanding sections that do not code for a specific protein. With CRISPR-Cas3 researchers can break down these plots and see what happens. damages than we understand and raise ethical issues. Nevertheless, the researchers behind this technique say it will take years before it is ready for therapeutic use.
