Web19 dec. 2024 · CRISPR-Cas9 is dus een genetische knipschaar die op een heel precieze manier stukjes DNA, bijvoorbeeld afwijkende stukjes die mensen ziek maken, kan wegknippen en op die manier het DNA kan veranderen (2). Het systeem werd ontdekt in de jaren 90 en biedt ongekende mogelijkheden. Web23 nov. 2024 · In addition to new Cas9 (a, b, c) and Cas12 (a, b, c, f, i) enzyme variants, we identified miniature CRISPR-associated nucleases in phages harboring both HNH and RuvC catalytic domains characteristic of Cas9. These miniature nucleases constitute phylogenetically distinct clades denoted as types II-x, -y, and -z (Figure 3 A).
