Applications in Medicine – NEET PYQ Focus

• Production of Insulin – Recombinant DNA technology.

• Vaccines – Genetically engineered vaccines for polio, hepatitis B.

• Monoclonal Antibodies – Used in diagnosis and treatment of diseases.

• Gene Therapy – Treating genetic disorders by replacing defective genes.

NEET questions often test medical applications of biotechnology and their mechanisms.

Applications in Agriculture – Important NEET Concepts

• Genetically Modified Crops – Bt cotton, pest-resistant and herbicide-tolerant plants.

• Biofertilizers – Nitrogen-fixing bacteria like Rhizobium and Azotobacter.

• Biopesticides – Bacillus thuringiensis (Bt) for pest control.

• Tissue Culture – Producing disease-free plants and improving crop yield.

Previous year papers may ask examples, mechanisms, and benefits of biotechnological applications in agriculture.

Applications in Industry – Key Concepts

• Fermentation Technology – Production of ethanol, citric acid, amino acids.

• Enzyme Production – Amylase, protease, and lipase for industrial use.

• Waste Management – Microbes used in treating industrial waste.

• Biofuel Production – Microbial production of bioethanol and biodiesel.

NEET PYQs often include industrial applications of microbial biotechnology.

Applications in Environment – NEET PYQ Focus

• Bioremediation – Microbes degrade pollutants like oil spills, pesticides.

• Wastewater Treatment – Microbes remove harmful chemicals from sewage.

• Nitrogen Fixation – Microbes enrich soil fertility naturally.

Previous year papers frequently test microbial roles in environmental sustainability.

Transgenic Organisms – Important Concepts

• Organisms containing foreign genes.

• Examples: Bt cotton (insect-resistant), transgenic fish, golden rice (vitamin A enriched).

• Applications: Improved yield, pest resistance, enhanced nutrition.

NEET questions often include examples and benefits of transgenic organisms.
