CRISPR Technologie: A Precision Tool for Genomic Medicine

CRISPR is a gene- editing platform derived from a accordive immune system. Te core acredients are a guide RNA (gRNA) that directs thate Cas9 nucleases to a specific DNA sequence, and the Cas9 enzyme that institutes a double- strand break at that site.
