We demonstrate that these ancient forms were much more flexible in their guide RNA and protospacer-adjacent motif requirements compared with modern-day Cas9 enzymes. Furthermore, anCas portrays a ...

Kylie Jenner has come under fire for allegedly treating Timothee Chalamet like a 'possession', with their relationship likened to that of a mother and son rather than a romantic couple, following ...

An artificial chimaera of crRNA and tracrRNA, the two bacterial RNA components that direct Cas9 to DNA sequences for cleavage. The first ∼20 bp of sgRNA (or crRNA) are variable and complementary to ...

That is a key feature that has made Cas9 such a powerful tool ... can only be directed to segments of DNA that are flanked by short motifs known as PAMs (protospacer adjacent motifs). TIGR Tas ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. In this study, we developed a novel diagnostic tool targeting ...

Prime editing (PE) is a highly versatile CRISPR–Cas9 genome editing technique. The current constructs, however, have variable efficiency and may require laborious experimental optimization. This study ...

Finally, some problems in CRISPR/Cas9 technology have been proposed ... the invading DNA is fragmented, and then a new protospacer is selected and integrated as a new spacer in the CRISPR array; (2) ...

The RNA-guided CRISPR/Cas9 system is a powerful tool for genome editing, but its targeting scope is limited by the protospacer-adjacent motif (PAM). To expand the ...
