Q2532. Match List-I with List-II regarding cloning vector components:
| Vector Component | Function |
|---|---|
| A. Origin of replication (ori) | i. Region containing several restriction sites for gene insertion |
| B. Selectable marker | ii. Sequence where DNA replication begins |
| C. Multiple cloning site (MCS) | iii. Gene that helps identify transformed cells (e.g., antibiotic resistance) |
| D. Promoter | iv. Sequence needed to initiate transcription of the inserted gene |
Explanation
The origin of replication is where DNA replication begins, a selectable marker identifies transformed cells, the multiple cloning site has several restriction sites for inserting a gene and the promoter starts transcription of the inserted gene. This gives A-ii, B-iii, C-i, D-iv.
Q2533. Which Paramara ruler is known for his literary contributions and is credited with writing works on medicine, architecture, and grammar?
Explanation
Raja Bhoja of the Paramara dynasty was a true polymath and a prolific writer. He is credited with authoring over eighty works on a vast range of subjects, including the "Samarangana Sutradhara" on architecture and the "Saraswatikanthabharana" on grammar. His immense literary and scientific contributions earned him the title "Kaviraja," making him one of the most celebrated intellectual figures in the history of medieval India.
Q2534. Match List-I with List-II and select the correct answer:
| Authority | To whom resignation is addressed |
|---|---|
| A. President | i. Deputy Speaker |
| B. Vice President | ii. President |
| C. Prime Minister | iii. Vice President |
| D. Speaker of Lok Sabha | iv. Chief Justice of India |
Explanation
Resignations for high constitutional offices follow a specific protocol. The President addresses his resignation to the Vice-President, who must immediately inform the Speaker of the Lok Sabha. The Vice-President, Prime Minister, and other Union ministers address their resignations to the President. However, the Speaker of the Lok Sabha submits his resignation to the Deputy Speaker, and vice versa, within the house.
Q2535. Which of the following does NOT constitute a part of the non-tax revenue of a State Government?
Explanation
Non-tax revenue for states includes interest receipts, royalties from minerals, and dividends from public enterprises. These are funds earned from services or assets rather than through taxation. In contrast, stamp duties and registration fees are categorized as a state’s own tax revenue. Understanding this distinction is important for analyzing the diverse ways in which state governments fund their operations and development projects.
Q2536. Consider the following statements about gene cloning vectors:
I. pBR322 is a widely used, artificially synthesized plasmid vector.
II. Plasmids can accommodate infinitely large fragments of foreign DNA.
III. Selectable markers allow the differentiation between recombinants and non-recombinants.
Which of the above statement(s) is/are correct?
I. pBR322 is a widely used, artificially synthesized plasmid vector.
II. Plasmids can accommodate infinitely large fragments of foreign DNA.
III. Selectable markers allow the differentiation between recombinants and non-recombinants.
Which of the above statement(s) is/are correct?
Explanation
pBR322 was indeed one of the first widely used artificial plasmid vectors. Selectable markers are essential for distinguishing between host cells that contain the recombinant plasmid and those that do not. However, plasmids have a limited capacity for the size of the foreign DNA they can carry; very large fragments require different vectors like BACs or YACs, making certain statements regarding their capacity incorrect.
Q2537. Consider the following events associated with the Chahamanas:
I. Foundation of Ajayameru (Ajmer).
II. Construction of Adhai Din Ka Jhonpra (originally a Sanskrit college).
III. Battle of Mahoba.
IV. First Battle of Tarain.
Which of the following represents the correct chronological order of these events?
I. Foundation of Ajayameru (Ajmer).
II. Construction of Adhai Din Ka Jhonpra (originally a Sanskrit college).
III. Battle of Mahoba.
IV. First Battle of Tarain.
Which of the following represents the correct chronological order of these events?
Explanation
The history of the Chahamanas followed a distinct chronological progression. It began with the foundation of Ajmer by Ajayaraja II. Later, Vigraharaja IV constructed a Sanskrit college in Ajmer, which was later converted into the Adhai Din Ka Jhonpra. Prithviraj III then expanded the empire, defeating the Chandelas at Mahoba in 1182, before his famous encounter with Muhammad Ghori at Tarain in 1191.
Q2538. Which of the following constitutional amendments made it mandatory for the President to accept the advice of the Council of Ministers?
Explanation
The 42nd Constitutional Amendment Act of 1976 amended Article 74 to state that the President shall act in accordance with the advice of the Council of Ministers. This made the cabinet’s advice legally binding on the President. Although the 44th Amendment later added a provision for one-time reconsideration, the principle that the President must ultimately follow the executive’s advice remains unchanged.
Q2539. What is the best characterization of a "Cess" in the context of Centre-State financial relations?
Explanation
A cess is a temporary tax levied for a specific purpose, such as education or infrastructure. Unlike regular taxes, the proceeds from a cess are not part of the divisible pool shared with the states. This allows the Union to target funding toward national priorities but has been a source of tension, as it reduces the overall share of revenue available for state devolution.
Q2540. The ampicillin resistance gene in plasmid pBR322 acts as a:
Explanation
In the plasmid pBR322, the ampicillin resistance gene functions as a selectable marker. When bacteria are grown on a medium containing the antibiotic ampicillin, only those cells that have successfully taken up the plasmid will be able to survive and form colonies. This allows researchers to easily identify and isolate the transformed bacteria from the vast majority of cells that did not receive the plasmid.Answer key for these questions
