1. What is Gene Editing?

   • Gene editing refers to precise modifications made to an organism’s DNA sequence.
   • It allows scientists to add, delete, or alter specific genes, opening up exciting possibilities for research, medicine, and agriculture.

2. Key Technologies for Gene Editing:

   • CRISPR-Cas9: A revolutionary tool that uses RNA-guided enzymes to target specific DNA sequences. It’s versatile, cost-effective, and widely used.
   • TALENs (Transcription Activator-Like Effector Nucleases): Custom-designed proteins that recognize specific DNA sequences and induce targeted changes.
   • ZFNs (Zinc-Finger Nucleases): Engineered proteins that bind to specific DNA sequences and introduce modifications.

3. Applications and Achievements:

   • Gene Knockout: Disabling specific genes to study their function.
   • Gene Correction: Fixing disease-causing mutations.
   • Gene Addition: Introducing new genes for therapeutic purposes.
   • Synthetic Biology: Creating artificial transcription factors for customized gene regulation.

4. Examples of Gene Editing Outcomes:

   • HIV Resistance: Researchers modified the CCR5 gene to confer resistance to HIV infection.
   • Sickle-Cell Anemia: Correcting the HBB gene mutation responsible for this blood disorder.
   • Spider Silk Production: Using gene-edited silkworms to produce spider silk for industrial applications.
