Assertion (A) and the other as Reason (R):
Assertion (A): The Constitution of India incorporates mechanisms like tax devolution and grants-in-aid to states.
Reason (R): Vertical fiscal imbalance is inherent in the constitutional design of revenue and expenditure assignments.
Explanation
The Indian Constitution acknowledges the inherent vertical gap between the revenue powers and expenditure duties of the Centre and States. To bridge this, the framework includes mandatory tax devolution and statutory grants. These mechanisms ensure that States have sufficient financial autonomy to manage their functions effectively despite having fewer independent revenue sources than the Centre.
Q2043. Given below are two statements, one labeled as
Assertion (A) and the other as Reason (R):
Assertion (A): The two strands of DNA can be separated by heating.
Reason (R): The strands of DNA are held together by weak hydrogen bonds between the nitrogenous bases.
Select the correct answer from the codes given below:
Assertion (A) and the other as Reason (R):
Assertion (A): The two strands of DNA can be separated by heating.
Reason (R): The strands of DNA are held together by weak hydrogen bonds between the nitrogenous bases.
Select the correct answer from the codes given below:
Explanation
Heating DNA provides thermal energy that disrupts the weak hydrogen bonds holding the two complementary strands together. Because these bonds are non-covalent, they break more easily than the covalent phosphodiester backbone when exposed to high temperatures. This separation process, known as denaturation, is fundamental for molecular techniques like polymerase chain reactions and occurs naturally during DNA replication.
Q2044. Bappa Rawal, the early ruler of the Guhila dynasty of Mewar, captured the fort of Chittor from which of the following rulers?
Explanation
Bappa Rawal is regarded as the first significant ruler of the Guhila dynasty in Mewar. Historical accounts and traditions state that he captured the strategic fort of Chittor from the Mori Rajput ruler, Man Mori, in the eighth century. This conquest laid the foundation for the long-standing Guhila and later Sisodia rule over Mewar, making Chittor their primary stronghold.
Q2045. The text Arthashastra by Kautilya is primarily a treatise on which of the following subjects?
Explanation
Kautilya’s Arthashastra is a comprehensive ancient Indian treatise focusing on political science and economic policy. It provides detailed instructions on the duties of a king, the organization of civil administration, and methods of warfare. The text serves as a manual for maintaining state sovereignty, managing public finances, and ensuring internal security through an elaborate system of laws and diplomatic strategies.
Q2046. Any dispute regarding the election of the President of India is inquired into and decided by:
Explanation
All doubts and disputes regarding the election of the President are inquired into and decided by the Supreme Court of India. Its decision is final. Such a petition can be filed by a candidate or twenty or more electors. Notably, the election cannot be challenged on the ground of any existing vacancy among the members of the presidential electoral college.
Q2047. Which of the following regions is NOT prominently associated with commercial dairy farming?
Explanation
Commercial dairy farming requires specialized infrastructure, cool climates for temperate cattle breeds, and proximity to large urban markets. The Equatorial Amazon Basin has high heat and humidity, which are unsuitable for large-scale dairy production. North-Western Europe, Canada, and South-Eastern Australia are leading regions due to favorable climates and advanced refrigeration and transportation networks.
Q2048. Which constitutional mechanism is primarily responsible for addressing the horizontal fiscal imbalance among States in India?
Explanation
Addressing the fiscal gap between states requires a formulaic approach that considers various socio-economic indicators. The Central Finance Commission uses criteria like income distance, population, and area to distribute the divisible pool of taxes. This ensures that resource-poor states receive more support, thereby promoting balanced regional development and reducing horizontal fiscal disparities across the Indian federation.
Q2049. Which among the following is not a function of DNA?
Explanation
DNA primarily functions as the carrier of genetic information and provides the instructions for synthesizing proteins through transcription and translation. While it controls cellular activities and replicates during division, it does not directly synthesize lipids. Lipid synthesis occurs in the cytoplasm, specifically within the smooth endoplasmic reticulum, mediated by various enzymes rather than direct DNA template instructions.
Q2050. Which of the following texts was not authored by Rana Kumbha?
Explanation
Rana Kumbha was a prolific scholar and patron of the arts, credited with writing works like Rasik Priya, Sudha Prabandh, and Sangit Raj. However, the text Raj Vallabh was actually authored by his chief architect, Mandana. While Mandana served under Kumbha’s patronage and designed several forts, the literary credit for this specific architectural treatise belongs to the architect himself.Answer key for these questions
