Summary:
- Indian scientists have engineered a new CRISPR protein called "Cas12a-VQR" that can more precisely edit genes compared to the original CRISPR-Cas9 system.
- This improved gene-editing tool has the potential to be used for treating genetic diseases and cancer by targeting and correcting faulty genes.
- The researchers demonstrated the effectiveness of Cas12a-VQR in editing genes related to sickle cell anemia and Duchenne muscular dystrophy, paving the way for future medical applications.
