Which body is the apex authority for approving the environmental release of genetically engineered organisms in India?
- A.Review Committee on Genetic Manipulation
- B.Genetic Engineering Appraisal Committee
- C.National Biodiversity Authority
- D.Indian Council of Agricultural Research
Correct answer
Explanation
The correct answer is B, the Genetic Engineering Appraisal Committee. Working under the Ministry of Environment, Forest and Climate Change, it is the apex committee under the rules of 1989 framed under the Environment (Protection) Act, 1986, and no genetically engineered organism may be released into the environment or used on a large scale without its clearance. Option A is wrong because the Review Committee on Genetic Manipulation, under the Department of Biotechnology, monitors research and small scale trials rather than commercial release. Option C is wrong because the National Biodiversity Authority, at Chennai, deals with access to biological resources and benefit sharing under the Act of 2002. Option D is wrong because ICAR conducts agricultural research and coordinates trials but grants no biosafety approval. Learn the pair as RCGM for research and GEAC for release.

Practice Questions
View allThe Bt gene used in Bt cotton is obtained from which organism?
- A.A virus
- B.A bacterium
- C.A fungus
- D.An alga
Show answer
The cry genes of Bt cotton come from Bacillus thuringiensis, a soil bacterium that forms crystal protein during sporulation; the protein is inactive as eaten but becomes a toxin in the alkaline gut of the bollworm, which is why the plant resists the pest.
Read the full explanation →Which genetically modified crop is approved for commercial cultivation in India?
- A.Bt brinjal
- B.Golden rice
- C.Bt cotton
- D.GM soybean
Show answer
Approved in 2002, it is the only genetically modified crop cleared for commercial cultivation by Indian farmers, and it is grown for fibre rather than as food.
Read the full explanation →The polymerase chain reaction, used to multiply a chosen segment of DNA, was invented by:
- A.Kary Mullis
- B.Alec Jeffreys
- C.Herbert Boyer
- D.Ian Wilmut
Show answer
He devised the polymerase chain reaction, which copies a selected stretch of DNA millions of times through repeated cycles of heating and cooling, using the heat resistant Taq polymerase, and he received the Nobel Prize in Chemistry for it.
Read the full explanation →Golden rice was developed to address the deficiency of which nutrient?
- A.Iron
- B.Vitamin A
- C.Iodine
- D.Vitamin D
Show answer
Golden rice was engineered to make beta carotene, the precursor from which the body forms vitamin A, in the edible part of the grain, and the pigment gives the rice its golden colour; the aim was to reduce night blindness among populations living mainly on rice.
Read the full explanation →Which of the following branches of botany deals with the development of improved plant varieties?
- A.Plant embryology
- B.Plant breeding
- C.Plant biochemistry
- D.Plant anatomy
Show answer
Plant breeding is the deliberate improvement of crops by choosing parents with desirable characters, crossing them, selecting among the progeny and multiplying the best lines; the high yielding wheat and rice varieties of the Green Revolution came from it, and modern breeding is often combined with tissue culture and marker…
