Ethical Issues and GEAC

NCERT grounding

Section 10.4 Ethical Issues of NCERT Class XII Biology, Chapter 10, is the syllabus anchor for this subtopic. The chapter has just discussed GM crops, recombinant insulin, gene therapy, molecular diagnosis and transgenic animals — and then deliberately ends on the moral and legal scaffolding required to keep the technology accountable. NIOS Chapter 30 (Biotechnology) covers genetic engineering but does not duplicate this ethical material, so NCERT is the single textual source. NEET 2018 Q.113 lifted the GEAC question almost verbatim from this section.

"Genetic modification of organisms can have unpredictable results when such organisms are introduced into the ecosystem."

NCERT XII Biology · §10.4 Ethical Issues

Why ethical regulation of biotechnology is needed

The opening sentence of section 10.4 is uncompromising — "the manipulation of living organisms by the human race cannot go on any further, without regulation." Some ethical standards are required to evaluate the morality of all human activities that might help or harm living organisms. Biotechnology raises two distinct classes of concern that NCERT keeps separate. The first is biological — genetic modification can bypass the natural reproductive isolation that normally prevents gene flow between species, and so the behaviour of a transgene in a new host and a new ecosystem cannot be fully predicted in advance. The second is socio-economic — when companies patent living organisms or extracts derived from traditional knowledge, indigenous communities are excluded from the value of their own bio-resources.

Both classes of concern arise from the same root fact — recombinant DNA technology lets us move genes in ways that nature, left alone, would not. A bacterial toxin gene can be introduced into a cotton plant, a daffodil carotenoid pathway into a rice endosperm, a human insulin coding sequence into E. coli. None of these crosses can occur naturally, because reproductive isolation, divergent chromosome numbers and incompatible developmental programmes would prevent them. Once that natural barrier is bypassed, the regulatory burden shifts onto humans — we have to decide what is safe, what is fair and what is permitted.

The unpredictability argument

The transgene works in the donor genome because everything around it — codon usage, regulatory proteins, metabolic precursors — has co-evolved with it. In the new host the transgene may be transcribed at a higher or lower rate, post-translationally modified differently, or interact unexpectedly with the host's own pathways. Once the GMO is released into an ecosystem, three additional unknowns layer on. Non-target organisms — pollinators, beneficial insects, soil microbes — may be exposed to the transgene product. Gene flow through pollen or seed can carry the transgene into wild relatives. And selection pressure can drive the evolution of resistant pests, eroding the value of the technology and changing community ecology.

GEAC — India's regulatory backstop

To address the biological concerns, the Indian Government has set up the Genetic Engineering Appraisal Committee (GEAC) — called the "Genetic Engineering Approval Committee" in older NCERT printings, and both names are accepted by NEET. GEAC functions under the Ministry of Environment, Forest and Climate Change (the NCERT phrase is "Ministry of Environment + Forests"). Its statutory mandate is twofold — it takes decisions regarding the validity of GM research, and it evaluates the safety of introducing GM organisms for public services. Every commercial release of a transgenic crop in India, including the original approval of Bt cotton hybrids in 2002, has had to pass GEAC clearance.

A common point of confusion is the distinction between GEAC and the Review Committee on Genetic Manipulation (RCGM). RCGM, under the Department of Biotechnology, clears small-scale and laboratory research — it is the everyday oversight layer for academic labs and contained experiments. GEAC sits above it, dealing with large-scale use and environmental release. NEET 2018 Q.113 listed RCGM, ICMR, CSIR and GEAC as four options and the correct answer was GEAC — because the question specifically asked about assessing the safety of introducing GMOs for public use, which is GEAC's remit, not RCGM's.

Safety concerns of GM food

The "safety of introducing GM-organisms for public services" that GEAC is mandated to evaluate is not abstract. Three concrete categories dominate the syllabus. First, allergenicity — when a transgene encodes a protein that the consumer population has never been exposed to, a fraction of individuals may mount IgE-mediated allergic responses. The classic non-NEET example is the StarLink corn episode, but the general principle is part of the NEET ethics framework. Second, antibiotic-resistance marker genes — early transformation protocols used genes such as those conferring kanamycin or ampicillin resistance to select transformed cells. The theoretical concern is that these markers, present in the food chain, could be transferred horizontally to gut microbes and compromise clinical antibiotics. Third, ecological effects on non-target organisms — pollen from Bt crops, for example, also reaches butterflies, lacewings and soil arthropods; the rule that Bt toxin is activated only in alkaline midgut conditions of lepidopteran pests limits but does not eliminate this concern.

Biopiracy and patenting traditional knowledge

The second arm of section 10.4 turns from biology to law. NCERT defines biopiracy in a single sentence — "biopiracy is the term used to refer to the use of bio-resources by multinational companies and other organisations without proper authorisation from the countries and people concerned without compensatory payment." The structural injustice the term names is concrete. Industrialised nations are financially rich but biodiversity-poor; developing and underdeveloped countries are biodiversity-rich and carry deep reserves of traditional knowledge about bio-resources. Without protective laws, that traditional knowledge can be exploited to develop modern commercial products with no compensation flowing back.

The Basmati rice case (1997)

Basmati is the textbook example. Rice has been grown in Asia for thousands of years; India alone has an estimated 200,000 varieties, and Basmati, distinct for its aroma and flavour, has 27 documented varieties grown in India, with references in ancient texts, folklore and poetry. In 1997, an American company — RiceTec — obtained patent rights on Basmati rice from the US Patent and Trademark Office. The "new" variety claimed as a novelty had actually been derived from Indian farmers' varieties crossed with semi-dwarf lines. Because the patent extended to functional equivalents, other people selling Basmati rice could in principle be restricted by it. India eventually challenged most of the broader claims, but the case became the canonical illustration of how a patent system can be turned against the originators of a resource.

Turmeric, neem and traditional medicine

Beyond Basmati, NCERT explicitly mentions that "several attempts have also been made to patent uses, products and processes based on Indian traditional herbal medicines, e.g., turmeric, neem." The wound-healing properties of turmeric and the antifungal and pesticidal properties of neem had been documented for centuries in Ayurvedic and folk practice, and challenges to patents on these substances became landmark cases for the global discussion on prior art and traditional knowledge. The lesson NCERT draws is operational, not rhetorical — "if we are not vigilant and we do not immediately counter these patent applications, other countries/individuals may encash on our rich legacy and we may not be able to do anything about it."

The Indian Patents Bill — second amendment

The legal instrument NCERT names in response is the second amendment of the Indian Patents Bill. The Indian Parliament cleared the second amendment "that takes such issues into consideration, including patent terms of emergency provisions, research, and development initiatives." In effect, the amendment updates patent law so that India can challenge patents based on its own traditional knowledge, can enforce compulsory licensing in public health emergencies, and can protect indigenous bio-resources from unauthorised commercial exploitation. Sitting alongside it, the international framework that this amendment plugs into is the Convention on Biological Diversity (1992), which recognises national sovereignty over genetic resources and the principle of prior informed consent and fair benefit-sharing with indigenous communities.
