How CRISPR-Cas9 Gene Editing Works: Target, Cut, Repair
CRISPR-Cas9 gene editing works by using a guide RNA to target a specific DNA sequence, a Cas9 enzyme to cut it, and the cell's natural repair mechanisms to alter the gene. This revolutionary technology is being applied to treat genetic diseases and improve crops, but faces challenges in delivery, precision, and ethical considerations, particularly regarding heritable germline edits.
