How does biotechnology impact healthcare?

Biotechnology revolutionizes healthcare by developing advanced treatments, personalized medicine, and innovative therapies like gene therapy and stem cell therapy, improving patient outcomes and disease management.

What are genetically modified organisms (GMOs)?

GMOs are organisms whose genetic material has been altered using biotechnology to enhance traits like pest resistance, nutritional value, and yield in crops and livestock.

How does biotechnology contribute to environmental sustainability?

Biotechnology promotes sustainability through bioremediation, waste management, and the development of biofuels and bioplastics, reducing pollution and reliance on fossil fuels.

What is gene therapy?

Gene therapy involves inserting, altering, or removing genes within an individual’s cells to treat or prevent diseases, offering potential cures for genetic disorders and certain cancers.

How is biotechnology used in agriculture?

Biotechnology enhances agriculture by developing GMOs, biofertilizers, and biopesticides, improving crop yield, resistance to pests and diseases, and soil fertility.

What are biopharmaceuticals?

Biopharmaceuticals are medical drugs produced using biotechnology, including proteins, antibodies, and vaccines, designed to treat diseases more effectively than traditional medicines.

How does fermentation work in biotechnology?

Fermentation uses microorganisms to convert organic substances into products like alcohol, antibiotics, and vitamins, playing a crucial role in food production and pharmaceuticals.

What are the ethical concerns in biotechnology?

Ethical concerns include genetic modification, cloning, gene therapy, and privacy issues related to genetic information, requiring careful consideration and regulation to address societal impacts.

How does biotechnology improve food production?

Biotechnology enhances food production through GMOs, improving crop yields, nutritional content, and resistance to pests, and through fermentation, creating diverse and nutritious food products.

What is CRISPR technology?

CRISPR is a powerful gene-editing tool that allows precise, targeted changes to DNA, revolutionizing genetic research, disease treatment, and agricultural development.
