How CRISPR Gene Editing Works

3-Second Blueprint (English)

1. CRISPR-Cas9 pairs a synthetic guide RNA with the Cas9 protein to locate and bind a specific target DNA sequence in cells.
2. Acting as molecular scissors, Cas9 cleaves the targeted DNA strand so scientists can add, delete, or alter genetic code.
3. High-precision genome editing enables genetic defect repair in medicine, functional gene studies, and resilient crops.
