Summary:

- The article describes a new gene editing technique called "Precision Genome Editing" (PGE) that can accurately and efficiently modify targeted DNA sequences in living cells.
- The PGE method utilizes a novel engineered enzyme system that can precisely identify and edit specific genomic regions with high fidelity, overcoming limitations of existing CRISPR-Cas9 technologies.
- Experiments demonstrated the PGE system's ability to correct disease-causing mutations in human cell lines and animal models, suggesting its potential for therapeutic applications in genetic disorders.
