Genetic Engineering — Key Concepts

TermMeaning
GMOGenetically Modified Organism — has DNA altered using genetic engineering (transgenic: gene from different species)
Genome editingPrecise modification of an organism's own DNA without introducing foreign genes (e.g., CRISPR)
TransgenicContains gene(s) from another species (e.g., Bt cotton has gene from Bacillus thuringiensis)
CisgenicContains gene from a sexually compatible species — no foreign species involved
Gene silencing (RNAi)Switching off a specific gene without removing it
CRISPR-Cas9Molecular "scissors" that cut DNA at precise locations; enables cheap, fast, accurate gene editing

Prelims Trap: GMOs and genome-edited organisms are NOT the same. GMOs contain foreign DNA (transgenic). Genome-edited organisms have their own DNA modified — no foreign genetic material is introduced. India's 2022 guidelines treat genome-edited plants (SDN-1 and SDN-2 categories) differently from GMOs, with a lighter regulatory pathway.


CRISPR-Cas9

How It Works

FeatureDetail
Full formClustered Regularly Interspaced Short Palindromic Repeats
Discovered byJennifer Doudna & Emmanuelle Charpentier — Nobel Prize in Chemistry, 2020
MechanismGuide RNA directs Cas9 enzyme to target DNA → Cas9 cuts the DNA → cell's repair mechanism edits it
AdvantagesPrecise, cheap, fast, versatile (works in plants, animals, humans)
LimitationsOff-target effects, mosaicism, ethical concerns in human germline editing

CRISPR Applications

DomainApplicationExample
MedicineGene therapy for genetic disordersCasgevy — first CRISPR therapy, US FDA approved 2023 (sickle cell disease)
India (Medicine)Indigenous CRISPR gene therapyBIRSA 101 — CRISPR therapy for Sickle Cell Disease by CSIR-IGIB (with Serum Institute)
AgricultureDrought/salinity toleranceIARI's Pusa Rice DST1 (drought-salinity tolerant, SDN-1 edit, approved 2025)
DiagnosticsRapid pathogen detectionFELUDA test (IGIB Delhi) — paper-based CRISPR COVID-19 test; 96% sensitivity, 98% specificity
IndustrialBio-based chemicals, biofuel feedstockEngineering microbes for biofuel production

India's CRISPR institutions: National Centre for Genome Editing & Training (NGETC) at Mohali; regulatory framework under National Guidelines for Gene Therapy (2019), CDSCO, NDCT Rules 2019.


GM Crops in India

Bt Cotton — India's Only Approved GM Crop

FeatureDetail
Approved2002 (Bollgard I); Bollgard II (two Bt genes: cry1Ac + cry2Ab) approved 2006
TechnologyContains cry1Ac gene (and later cry2Ab) from Bacillus thuringiensis → produces Bt toxin → kills bollworm larvae
Adoption~95% of India's cotton area is now Bt cotton
ImpactCotton production tripled (13.6 million bales in 2002 → 35.4 million bales by 2014); India became world's largest cotton producer
ControversyPink bollworm resistance emerged (Gujarat, Maharashtra); seed monopoly concerns (Monsanto/Bayer); farmer suicide debate (correlation, not proven causation)

For Mains: The Bt cotton story is nuanced. Initial benefits were real — tripled yields, ~70% reduction in pesticide use against bollworm. But pink bollworm resistance development and dependence on proprietary seeds created new vulnerabilities. Use as a case study of technology adoption — benefits vs risks of monoculture and corporate dependency.

Bt Brinjal — Moratorium Since 2010

FeatureDetail
Developed byMahyco (Maharashtra Hybrid Seeds Company), Jalna
GEAC approvalOctober 14, 2009 — cleared for commercial cultivation
MoratoriumFebruary 9, 2010 — Environment Minister Jairam Ramesh imposed indefinite moratorium
ReasonNo overriding food security urgency; opposition from 9 state governments; widespread public concern; brinjal is India's centre of origin (gene flow to wild relatives risk)
Current statusMoratorium continues in India; however, Bangladesh has successfully cultivated Bt Brinjal commercially since 2014; 2020 — GEAC allowed confined field trials of indigenous Bt Brinjal varieties in 8 states

GM Mustard (DMH-11) — Ongoing Controversy

FeatureDetail
Developed byDelhi University (Prof. Deepak Pental's team)
TechnologyHybrid mustard using barnase-barstar gene system from Bacillus amyloliquefaciens
Yield advantage~28% higher than national check variety
GEAC approvalOctober 2022 — approved for environmental release
Supreme CourtSplit verdict (2024) — Justice Nagarathna invalidated; Justice Karol upheld. Referred to larger bench
ContextIndia imports 55–60% of edible oil; DMH-11 could boost domestic production

Why it matters: DMH-11 could be India's second GM crop after 22 years. The debate combines science (safety), politics (anti-GM activism), economics (edible oil import burden), and federalism (states like Rajasthan oppose). A classic multi-dimensional Mains question.

Genome-Edited Crops — India's New Pathway (2025)

India approved its first genome-edited crop varieties in 2025 — NOT GMOs (no foreign DNA; SDN-1 category edit):

VarietyDeveloped byFeature
Pusa Rice DST1IARI, New DelhiDrought and salinity tolerance
DRR Dhan 100IIRR, HyderabadImproved grain quality and yield

India's 2022 genome editing guidelines exempt SDN-1 and SDN-2 edits from the full GMO regulatory process — creating a faster innovation pathway for crops that only modify the plant's own DNA.

Common Prelims Mistake: Bt Cotton is the ONLY commercially approved GM crop in India (since 2002). Bt Brinjal was approved but placed under moratorium (2010). GM Mustard got GEAC approval (2022) but is in legal limbo (SC 2024). Genome-edited crops (Pusa Rice DST1, DRR Dhan 100) are NOT GMOs — different regulatory category.


Regulatory Framework for GMOs in India

Key Laws

LegislationRole
Environment Protection Act, 1986Umbrella law for GMO regulation
Rules for Manufacture, Use, Import, Export and Storage of Hazardous Microorganisms/GMOs, 1989Primary biosafety regulatory framework; notified under EPA 1986
Food Safety and Standards Act, 2006Regulates GM food imports and labelling
Biological Diversity Act, 2002Governs access to genetic resources

International: Cartagena Protocol on Biosafety

FeatureDetail
NatureSupplementary agreement to the CBD — focused on safe transfer/handling/use of Living Modified Organisms (LMOs)
AdoptedJanuary 29, 2000 (Montreal); In force: September 11, 2003
IndiaIndia is a Party
Key principleAdvance Informed Agreement (AIA): Exporting country must notify importing country and get consent before first transboundary movement of an LMO for release into the environment
Precautionary principleUncertainty about risks does not preclude taking preventive measures
Biosafety Clearing House (BCH)Online platform for exchanging biosafety information globally

India's Rules 1989 under EPA 1986 are broadly aligned with the Cartagena Protocol's requirements for risk assessment and information exchange.

Key Biosafety Risks

RiskExplanation
Horizontal gene transferTransgenes may transfer to soil bacteria or wild plant relatives, creating ecological changes
Biodiversity impactHerbicide-tolerant GM crops may lead to monocultures, reducing agro-biodiversity
AllergenicityForeign proteins in GM food could trigger allergic reactions
Resistance developmentInsects/weeds can develop resistance to Bt toxin or herbicide → "super-pests" and "super-weeds"
Cross-pollinationGM pollen can contaminate non-GM and organic crops in neighbouring fields

Six-Tier Regulatory Structure

BodyLevelRole
RCGM (Review Committee on Genetic Manipulation)DBTReviews research proposals involving GMOs
GEAC (Genetic Engineering Appraisal Committee)MoEFCCApex body — approves environmental release of GMOs; renamed from "Approval" to "Appraisal" in 2010
IBSC (Institutional Biosafety Committee)InstitutionMonitors recombinant DNA research at each institution
SBCC (State Biotechnology Coordination Committee)StateMonitors GMO use at state level
DLC (District Level Committee)DistrictMonitors field trials at district level
RDAC (Recombinant DNA Advisory Committee)DBTAdvises on recombinant DNA research policy

Prelims Fact: GEAC (under MoEFCC) is the apex approval body. RCGM (under DBT) handles research-stage approvals. Don't confuse the two. Agriculture is a State subject, but GM crop regulation is under EPA 1986 (Union law) — creating Centre-state tension.

Genome Editing Guidelines — SDN Categories (2022)

CategoryDescriptionRegulatory Pathway
SDN-1Small deletions/insertions; no foreign DNAExempt from GMO regulations — treated like conventional breeding
SDN-2Small changes using a DNA template from same/related speciesLighter regulation than GMOs
SDN-3Insertion of foreign DNA using CRISPRRegulated as full GMO (GEAC process required)

Genome Sequencing Projects

ProjectLead AgencyDetails
IndiGenCSIR (IGIB Delhi + CCMB Hyderabad)WGS of 1,029 Indians; identified 55.9 million SNVs; 32.23% unique to India
GenomeIndiaDepartment of Biotechnology (DBT)WGS of 10,074 individuals from 83 distinct populations (99 communities); data opened by PM Modi on 9 January 2025; 135 million+ genetic variations identified

Why Genome India matters: Global genomic databases are dominated by European-ancestry data. Indians are genetically distinct and diverse. Without an Indian reference genome, precision medicine cannot work for India's population.


Biotech in Agriculture — Beyond GM Crops

One Health Approach

AspectDetail
ConceptIntegrated approach recognising the interconnection between human health, animal health, and the environment
Relevance~75% of emerging infectious diseases are zoonotic in origin (COVID-19, SARS, Nipah, Ebola)
India's AdoptionNAP-AMR (2017) adopted One Health framework; inter-ministerial coordination between MoHFW, MoAHD, MoEFCC
Key Focus AreasZoonotic diseases, food safety, antibiotic resistance, environmental health
Research InitiativeICMR-DBT-ICAR One Health Consortium (2021) — collaborative surveillance and research network

Exam Tip: For any UPSC answer on COVID-19, AMR, or avian flu, invoke the One Health framework. Key fact: ~75% of emerging infectious diseases are zoonotic. India's NAP-AMR (2017) explicitly adopted this approach. The institutional challenge is inter-ministerial coordination between MoHFW, MoAHD, and MoEFCC.


Antimicrobial Resistance (AMR)

ParameterDetail
NAP-AMR 1.0Launched 19 April 2017; aligned with WHO Global Action Plan on AMR
NAP-AMR 2.0Launched in 2024; updated strategy with human health, research, animal husbandry, and environment sectors
Global scale~1.27 million deaths/year (Lancet, 2022); could cause 10 million/year by 2050
India's burdenAmong world's highest antibiotic consumers; ~119,000 MDR/RR-TB cases/year
ESKAPE pathogensEnterococcus, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter
SurveillanceICMR's AMR Surveillance Network (AMRSN); data to WHO's GLASS system
Root causesOver-the-counter antibiotics; irrational prescriptions; antibiotic overuse in agriculture/veterinary use

Ethical and Social Dimensions

IssueDiscussion Points
Food safetyAre GM foods safe? Scientific consensus: yes (approved varieties). Public perception differs
Farmer autonomyGM seeds are often patented → farmers cannot save seeds → corporate dependency
Biodiversity riskGene flow from GM crops to wild relatives could create "superweeds"
LabellingIndia requires GM food labelling but enforcement is weak
Gene editing ethicsCrops (widely accepted) → Animals (debated) → Human embryos (banned in most countries)
Access and equityWill biotech benefits reach smallholders or only corporate farms?
BiopiracyExploitation of indigenous genetic resources without benefit-sharing

Biopiracy Landmark Cases

Turmeric Patent (1995–1997):

  • US Patent No. US5401504A granted to University of Mississippi Medical Centre (1995) for use of turmeric in wound healing
  • CSIR challenged it, proving turmeric's wound-healing use was documented in ancient Ayurvedic texts — not novel
  • USPTO revoked the patent in 1997 — one of the earliest successful biopiracy challenges

Neem Patent (1994–2005):

  • European Patent Office (EPO) granted Patent EP436257 to W.R. Grace & Co. and USDA on a neem-based fungicide (1994)
  • Dr. Vandana Shiva and activists filed opposition citing India's traditional neem use
  • EPO revoked the patent in May 2000; appeal confirmed final revocation in 2005

Traditional Knowledge Digital Library (TKDL)

FeatureDetail
Established2001 — joint initiative of CSIR and Ministry of AYUSH
PurposeDocument India's traditional medicinal knowledge in machine-readable format accessible to global patent offices
Content~0.9 million formulations from Ayurveda, Unani, Siddha, and Yoga texts
LanguagesAvailable in English, French, German, Spanish, and Japanese
AccessProvided to patent examiners at USPTO, EPO, JPO, UKIPO, CIPO as prior art database
ImpactCited in 200+ patent examination proceedings; prevented grant of patents on traditional Indian knowledge

TKDL represents India's "defensive protection" strategy — documenting traditional knowledge as prior art to prevent others from patenting it, rather than patenting it (which may not meet novelty criteria).

Recent Developments (2024–2026)

BioE3 Policy — India's Biomanufacturing Strategy (August 2024)

The Union Cabinet approved the BioE3 (Biotechnology for Economy, Environment, and Employment) Policy in August 2024, implemented by the Department of Biotechnology (DBT). The policy identifies six strategic sectors for high-performance biomanufacturing: (a) bio-based chemicals and enzymes, (b) functional foods and smart proteins, (c) precision biotherapeutics (gene therapy, mRNA, cell therapy), (d) climate-resilient agriculture, (e) carbon capture and utilisation, and (f) marine and space biotech.

BioE3 positions India to become a global biomanufacturing hub alongside the USA's National Biotechnology and Biomanufacturing Initiative (2022) and the EU's Green Deal bioeconomy strategy. India's bioeconomy reached approximately $130 billion in 2024 — the government targets $300 billion by 2030. BioE3's precision biotherapeutics vertical includes gene therapies for haematological diseases (Hemophilia A, Thalassaemia) and mRNA therapeutics — directly supported by DBT's clinical trial funding.

UPSC angle: BioE3 Policy, DBT role, six strategic sectors, India's bioeconomy target ($300 billion by 2030), and gene therapy pipeline are Mains GS-3 content.


India's BIRSA 101 — First Indigenous CRISPR Therapy for Sickle Cell Disease (November 2025)

India launched its first indigenous CRISPR-based gene therapy for sickle cell disease — named "BIRSA 101" (a tribute to Bhagwan Birsa Munda) — in November 2025, under the Ministry of Tribal Affairs in partnership with AIIMS Delhi and IGIB (Institute of Genomics and Integrative Biology). BIRSA 101 uses the Indian-developed enFnCas9 enzyme (enhanced, patented by IGIB) for precision editing of the beta-globin gene.

This makes India one of the few countries globally with an indigenous CRISPR therapy in clinical use. The Casgevy therapy (by Vertex Pharmaceuticals and CRISPR Therapeutics), approved in the UK (2023) and USA (2023), costs over $2.2 million per patient — making it inaccessible for India's estimated 30 million sickle cell carriers. BIRSA 101's domestic development aims to make curative therapy affordable.

UPSC angle: BIRSA 101, sickle cell disease burden in India (Tribal population particularly affected), IGIB's enFnCas9, and affordable gene therapy as a public health goal are Mains GS-3/GS-2 content.


GM Crops — Mustard DBH-11 and Regulatory Updates 2024

India's only commercially approved GM crop remains Bt cotton (since 2002). In 2024, the Genetic Engineering Appraisal Committee (GEAC) continued its review of GM Mustard (DMH-11, developed by Delhi University). The Supreme Court had directed the government to disclose the complete regulatory file, and the issue remained in litigation with environmental groups challenging the herbicide-tolerance aspect of DMH-11.

The broader GMO regulatory debate gained urgency as Bt Brinjal (approved in Bangladesh in 2014 and showing yield benefits) and drought-tolerant GM maize are pending Indian review. BioE3 Policy's "climate-resilient agriculture" vertical could accelerate approvals for drought/heat-tolerant crop varieties, though the food safety-environmental tradeoff debate continues.

UPSC angle: GM Mustard status (GEAC review, SC direction), India's GMO regulatory framework (GEAC, RCGM, IBSC), and the DMH-11 herbicide tolerance controversy are Prelims and Mains content.


Vocabulary

Genome

  • Pronunciation: /ˈdʒiː.nəʊm/
  • Definition: The complete set of genetic material (DNA or, in some viruses, RNA) present in a cell or organism, containing all the information needed for that organism's development and function.
  • Origin: Coined by German botanist Hans Winkler in 1920, as a blend of German Gen ("gene") and Chromosom ("chromosome").

CRISPR

  • Pronunciation: /ˈkrɪs.pər/

  • Origin: Contraction of biological fertiliser; bio- from Greek bios ("life").

Key Terms

Genetic Modification

  • Pronunciation: /dʒəˈnɛt.ɪk ˌmɒd.ɪ.fɪˈkeɪ.ʃən/
  • Definition: The deliberate alteration of an organism's DNA using laboratory techniques — including insertion of foreign genes (transgenic), deletion of existing genes, or site-specific modification using CRISPR-Cas9. The key regulatory distinction: traditional GM (foreign DNA, full GEAC process) vs genome editing SDN-1/SDN-2 (no foreign DNA, lighter regulation).
  • Context: Bt cotton (cry1Ac gene) is India's only approved GM crop since 2002. Bt Brinjal was approved by GEAC October 2009 but placed under moratorium February 2010 (Jairam Ramesh). GM Mustard (DMH-11) received GEAC approval October 2022 but faces SC legal challenge (split verdict 2024).
