CRISPR gene editing tools are a groundbreaking technology that allows precise modification of DNA within living organisms. It works by using a guide RNA to target specific DNA sequences, while the Cas9 enzyme cuts the DNA at the desired location. This enables scientists to add, delete, or modify genes with high accuracy. CRISPR is widely used in research, medicine, and agriculture for gene therapy, genetic modification of crops, and disease prevention. It is known for its efficiency, simplicity, and versatility compared to previous gene-editing methods.
