Why this matters now
Biotech is tested for its applications (medical, agricultural, industrial), GM crops, India’s bio-economy/BioE3 policy and the regulatory/bioethics debate — a high-yield GS-3 area.
Branches and applications
- Red (medical) — vaccines, recombinant insulin, gene therapy, diagnostics;
- Green (agricultural) — GM/Bt crops, biofertilisers, tissue culture;
- White (industrial) — enzymes, biofuels, bioplastics;
- Blue (aquatic) — marine bioresources.
GM crops in India
Genetically Modified (GM) crops are made by inserting desired genes. India approved Bt cotton (its only commercial GM crop) for pest resistance; Bt brinjal faced a moratorium and GM mustard (DMH-11) remains contested. The regulator is the GEAC (Genetic Engineering Appraisal Committee).
India’s bio-economy and bioethics
India’s bio-economy is growing rapidly; the BioE3 (Biotechnology for Economy, Environment and Employment) Policy promotes bio-manufacturing and high-performance biomanufacturing. Concerns include biosafety, ethics (gene editing of humans), biopiracy and equitable access — regulated by the GEAC, the Biological Diversity Act and (proposed) DNA/biotech frameworks.

Frequently asked questions
What is biotechnology?
The use of living organisms and biological systems to develop useful products in health, agriculture and industry.
Which GM crop is commercially grown in India?
Bt cotton is the only GM crop approved for commercial cultivation in India.
Who regulates GM crops in India?
The Genetic Engineering Appraisal Committee (GEAC) under the environment ministry.
What is the BioE3 policy?
The Biotechnology for Economy, Environment and Employment policy, which promotes bio-manufacturing and India’s bio-economy.
