Figure 1: CRISPR–Cas systems identified in uncultivated organisms. Figure 2: ARMAN-1 CRISPR array diversity and identification of the ARMAN-1 Cas9 PAM sequence. Figure 3: CRISPR–CasX is a dual ...

This insight reveals how to tune Cas removal, contributing to future CRISPR applications. "Polarity of the CRISPR Roadblock to Transcription" published Dec. 5 in Nature Structural & Molecular Biology.

The second part of the defense mechanism is a set of enzymes called Cas (CRISPR-associated proteins), which can precisely snip DNA and slice the hell out of invading viruses. Conveniently ...

The six types of CRISPR systems work roughly the same way: A CRISPR RNA identifies foreign genetic code, which triggers a cas enzyme to mediate an immune response, often snipping off the invader ...

Researchers have uncovered a serious side effect of using the CRISPR-Cas gene scissors. A molecule designed to make the process more efficient destroys parts of the genome. Genome editing with ...

Scientists have categorized different types of CRISPR systems into two classes based on how their Cas nucleases function. In class 1 (types I, III, and IV), different Cas proteins form a complex ...

Yet others, called base editors, change one letter of the DNA code to another. So why do we call it CRISPR? Cas proteins are used by bacteria to destroy viral DNA. They add bits of viral DNA to ...

With the first medical therapy approved and systems like CRISPR-Cas showing up in complex cells, there’s a lot happening in the genome editing field. By Amber Dance/Knowable Magazine Published ...

This insight reveals how to tune Cas removal, contributing to future CRISPR applications. "Polarity of the CRISPR Roadblock to Transcription" published Dec. 5 in Nature Structural & Molecular Biology.

Genome editing with various CRISPR-Cas molecule complexes has progressed rapidly in recent years. Hundreds of labs around the world are now working to put these tools to clinical use and are ...
