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 ...

CRISPR-Cas9 is not the first method available to scientists for modifying DNA; it is by far, however, the easiest to use. With CRISPR-Cas9, the crRNA/tracrRNA sequence or an artificial guide RNA ...

The Cas9 protein is the most widely used by scientists. This protein can easily be programmed to find and bind to almost any desired target sequence, simply by giving it a piece of RNA to guide it ...

New research from an international team, including a Penn State researcher, demonstrates—for the first time—the use of CRISPR-Cas9 gene editing in kissing bugs and opens the door to research ...
