(Courtesy of Stanley Qi) CRISPRKit works in a similar way, though it employs dCas9, or “dead” Cas9, a deactivated version of the Cas9 enzyme unable to cut DNA. “Whereas CRISPR-Cas9 is ...

CRISPR-Cas9 genome editing exploits the CRISPR-Cas system to modify a genome in a targeted manner. Guided by RNA, the Cas9 endonuclease breaks DNA at a target sequence. Imprecise repair of the ...

Get Instant Summarized Text (Gist) New CRISPR-Cas systems have been identified, enhancing the gene editing toolkit. A notable system, SubCas9, from bacteria in dairy cows, is efficient, small, and ...

CRISPR is incredibly robust in terms of cutting DNA and targeting ... CRISPRa uses a version of Cas9 that is inactive (dCas9). It cannot cut DNA, but it progressively binds to targets using guide RNAs ...

The researchers wanted to test if they could reverse these changes using epigenomic editing. So, they employed the CRISPR-dCas9 system. Like its widely used sister system CRISPR-Cas9, CRISPR-dCas9 ...

Following these screens, the researchers tested a third tool — a CRISPR-based demethylase (Tet1-dCas9). This enzyme removes methylation, a chemical mark that silences the maternal allele.

CRISPR is a technology that can be used to edit genes and, as such, will likely change the world. The essence of CRISPR is simple: it’s a way of finding a specific bit of DNA inside a cell.
