WebDescription. GenCrispr NLS-Cas9-D10A Nickase is a mutation form of Cas9 Nuclease. Cas9 nuclease is an RNA-guided endonuclease that can catalyze cleavage of double stranded DNA. This kind of targeted nuclease is a powerful tool for genome editing with high precision. Cas9 nuclease cleaves the double strand DNA generating two break sites … WebCRISPR nickases make genome editing more accurate in a different way. CRISPR enzymes like Cas9 usually cut both of DNA’s two strands. Researchers can mutate one of Cas9’s cutting domains to stop it from working, turning the enzyme into a nickase. A nickase makes a cut in just one strand, which is called a nick.
