WebHOW DOES CRISPR WORK? Scientists select an appropriate Cas enzyme and design a gRNA targeting a genomic site. After synthesis, gRNA is combined with the Cas enzyme, forming a ribonucleoprotein (RNP). The RNP is delivered to cells by various means such as electroporation, and genome editing takes place inside cells. Cas9 An enzyme that geneticists are now using to help edit genes. It can cut through DNA, allowing it to fix broken genes, splice in new ones or disable certain genes. Cas9 is shepherded to the place it is supposed to make cuts by CRISPRs, a type of genetic guides. The Cas9 enzyme came from bacteria.
