# CRISPR-based enzyme shreds DNA to destroy cancer cells

Scientists have discovered that a CRISPR-associated enzyme can target and fragment the DNA of cancer cells, leading to their death. This unconventional approach exploits a natural bacterial defense mechanism to attack tumors from within. The finding opens new avenues for cancer therapy by directly eliminating malignant cells rather than simply inhibiting their growth.
