Explanation
A Prime Minister who is a member of the Rajya Sabha can participate in all proceedings of both Houses but can only vote in the house to which they belong. Since a no-confidence motion is introduced and voted upon exclusively in the Lok Sabha, such a Prime Minister cannot vote in their own favor or against the motion during the final division.Explanation
The Comptroller and Auditor General is a constitutional authority responsible for auditing the accounts of both the Union and the State governments. This independent audit ensures that public money is spent legally and efficiently. By providing detailed reports to the respective legislatures, the CAG promotes fiscal accountability and transparency, which are essential for the healthy functioning of a federal financial structure.Explanation
A thermocycler, also known as a PCR machine, is a specialized laboratory instrument designed to automatically cycle through the precise temperature changes required for the denaturation, annealing, and extension steps of the Polymerase Chain Reaction. By accurately and rapidly heating and cooling the reaction tubes, the device allows for the efficient and repeated amplification of DNA sequences without the need for manual intervention.Explanation
"Nainsi ri Khyat," written by the seventeenth-century scholar Muhnot Nainsi, is a comprehensive record of the various Rajput clans. In his work, Nainsi mentions that the Guhila dynasty of Mewar had 24 different branches. This detailed classification provides insights into the historical migration and fragmentation of the clan as it established various small principalities across Rajasthan and neighboring regions over several centuries.Explanation
A motion of no-confidence can only be introduced and passed in the Lok Sabha. This is because the Council of Ministers is collectively responsible to the lower house, which is directly elected by the people. If passed, the entire government must resign. The Rajya Sabha does not have the power to remove the government through such a motion, reinforcing the lower house’s supremacy.Explanation
The tax effort criterion is designed to encourage states to maximize their own revenue generation. It rewards states that show higher efficiency in collecting taxes compared to their estimated fiscal capacity. By including this in the devolution formula, the Finance Commission motivates states to improve their administrative systems and reduce tax evasion, thereby strengthening their own financial health and reducing dependency.Explanation
Plasmids are small, circular, double-stranded DNA molecules found in many bacteria, separate from the main chromosomal DNA. They are capable of self-replication and often carry genes that provide a survival advantage, such as antibiotic resistance. Because they are easy to isolate and manipulate, plasmids are the most commonly used vectors in genetic engineering for carrying and cloning foreign DNA segments in host cells.I. Nagabhata I established his capital at Bhinmal.
II. Vatsaraja is often considered the real founder of the Pratihara empire.
III. Rajasekhara was the court poet of Vatsaraja.
Which of the above statement(s) is/are correct?
Explanation
The Gurjara-Pratihara dynasty’s rise began with Nagabhata I, who established his base at Bhinmal. However, Vatsaraja is often considered the real architect of the empire as he successfully participated in the Tripartite Struggle for Kannauj. While Rajashekhara was indeed a famous court poet, he served much later rulers like Mahendrapala I and Mahipala I, rather than Vatsaraja himself, during the dynasty’s cultural peak.Explanation
Following the 44th Amendment Act of 1978, the President can only proclaim a National Emergency under Article 352 after receiving a written recommendation from the Union Cabinet. This requirement ensures that the decision is a collective one involving senior ministers, rather than being the Prime Minister’s unilateral choice. This serves as a vital safeguard against the potential misuse of emergency powers.Answer key for these questions
