Sentences with phrase «endonuclease enzymes»
Cas9 is the endonuclease enzyme part of CRISPR / Cas9 system that cuts the DNA, while RNA is the CRISPR guide, directing the enzyme to specific sites in the genome so that precise genome edits are possible.

These elements insert themselves into the host genome using two enzymes that they encode for themselves: an endonuclease that cleaves the host chromosome in a specified location, and a reverse transcriptase that copies the retrotransposon's DNA back into the host genome.
Those genes make endonucleases — DNA - cutting enzymes that target one spot in an organism's entire genetic catalog, or genome.
«If it is to work properly, this cutting requires at least one endonuclease, an enzyme with very specific characteristics.»
This is called restriction and the endonuclease in question is the restriction enzyme.
While native CRISPR / Cas systems have a variety of enzymes responsible for processing foreign DNA as well as the RNA guides required for endonuclease function, when used for genome engineering, the only CRISPR protein required is the Cas9 endonuclease or a variant thereof.
