Explanation
Cabinet Committees are extra-constitutional bodies that are not mentioned in the original text of the Constitution. They are created by the Prime Minister under the Government of India (Transaction of Business) Rules, 1961.

Their number, composition, and functions vary depending on the Prime Minister’s requirements.
Q2563. A State government decides to launch an ambitious welfare scheme providing free electricity, which strains its budget. According to fiscal federal principles and the FRBM Act, what is the most immediate constraint the state will face if it attempts to fund this through unlimited borrowing?
Explanation
State governments are subject to fiscal discipline frameworks that limit their annual borrowing to a specific percentage of their Gross State Domestic Product. This prevents excessive debt accumulation that could destabilize the national economy. If a state launches expensive welfare schemes, it must manage the expenditure within these strictly defined and monitored constitutional and statutory borrowing limits to ensure long-term fiscal sustainability and stability.
Q2564. The primary purpose of gene cloning in biotechnology is to:
Explanation
The fundamental goal of gene cloning is to isolate a specific DNA sequence and produce many identical copies of it. This allows scientists to obtain enough material to study the genes structure, sequence, and function, or to use the cloned DNA for practical applications like gene therapy, the creation of transgenic organisms, or the industrial-scale production of valuable proteins like hormones.

Q2567. Match List-I with List-II regarding genetically modified crops:
| GM Crop | Specific Trait |
|---|---|
| A. Bt Cotton | i. Delayed ripening |
| B. Golden Rice | ii. Insect resistance against bollworms |
| C. Flavr Savr Tomato | iii. Herbicide tolerance and higher yield |
| D. GM Mustard (DMH-11) | iv. Biofortified with Vitamin A precursor |
Explanation
Characteristics of Genetically Modified Crops A. Bt Cotton provides resistance against bollworms. B. Golden Rice is biofortified with Vitamin A precursors. C. Flavr Savr Tomato was engineered for delayed ripening. D. GM Mustard DMH-eleven exhibits herbicide tolerance. These traits illustrate how biotechnology can enhance agricultural productivity, nutritional value, and shelf life of food through targeted genetic modifications across different biological species.
Q2568. Which Kachwaha ruler performed the Ashvamedha Yajna, considered the last such grand Vedic sacrifice performed by a Hindu king?
Explanation
Sawai Jai Singh II of Jaipur was a unique ruler who sought to revive ancient Vedic traditions.

Q2569. Consider the following statements regarding Bt cotton:
I. It contains cry genes isolated from the bacterium Bacillus thuringiensis.
II. The Bt toxin protein is produced in the plant as an inactive protoxin.
III. The toxin is activated by the alkaline pH of the insect gut.
IV. It is currently approved for commercial cultivation in India.
Which of the above statement(s) is/are correct?
I. It contains cry genes isolated from the bacterium Bacillus thuringiensis.
II. The Bt toxin protein is produced in the plant as an inactive protoxin.
III. The toxin is activated by the alkaline pH of the insect gut.
IV. It is currently approved for commercial cultivation in India.
Which of the above statement(s) is/are correct?
Explanation
Bt cotton is a transgenic variety containing cry genes from Bacillus thuringiensis. The plant produces the Bt toxin in an inactive protoxin form, which is harmless to the plant and humans. However, when an insect consumes the plant tissue, the alkaline pH of its gut activates the toxin, leading to pore formation and death. This crop is currently commercially cultivated in India.
