Biotechnology impacts human health in multiple ways:
1. Diagnostics: Enhanced techniques like PCR and genetic screening for early disease detection (e.g., cancer, genetic disorders).
2. Therapeutics: Production of recombinant proteins (e.g., insulin, monoclonal antibodies) for treating diabetes, cancer, and autoimmune diseases.
3. Vaccines: Development of safer, effective vaccines (e.g., mRNA vaccines for COVID-19).
4. Gene therapy: Correcting genetic defects (e.g., treating SCID, cystic fibrosis).
5. Personalized medicine: Tailoring treatments based on genetic profiles.
6. Ethical concerns: Issues like genetic privacy, designer babies, and unequal access to biotechnological advances.
