Q2592. Man Singh I was associated with the promotion of which specific art form in Amber, originally brought from Persia via Lahore?
Explanation
Man Singh I of Amber is credited with introducing several Persian-influenced art forms to Rajasthan. While serving in the Mughal administration, he brought skilled craftsmen from Lahore to Amber to promote the arts of Meenakari, which is enamel work on metal, and Blue Pottery. These crafts flourished under royal patronage and eventually became world-famous hallmarks of Jaipur’s rich and vibrant artistic and cultural heritage.
Q2593. Which chromosome was the last to be completely sequenced in the Human Genome Project (completed in 2006)?
Explanation
Chromosome 1 is the largest human chromosome, containing approximately 3,000 genes. Due to its sheer size and complexity, it was the last chromosome to be completely sequenced as part of the Human Genome Project. The finished sequence of Chromosome 1 was officially published in May 2006, marking the final milestone in the primary sequencing phase of the thirteen-year long international effort.
Q2594. Match List I with List II and select the correct answer using the codes given below:
| Rulers of Bundi/Kota | Key Contributions/Events |
|---|---|
| A. Rao Surjan Hada | i. First independent ruler of Kota |
| B. Madho Singh | ii. Signed the treaty with the British for Kota |
| C. Umed Singh | iii. Surrendered Ranthambore to Akbar |
| D. Zalim Singh (Dewan) | iv. Constructed the Chitrashala in Bundi |
Explanation
The Hada rulers of Bundi and Kota each contributed significantly to their history. Rao Surjan Hada surrendered Ranthambore to Akbar, initiating a long alliance. Madho Singh became the first independent ruler of Kota in 1631. Umed Singh of Bundi is famous for building the Chitrashala, a masterpiece of painting. Finally, Zalim Singh, the powerful Dewan of Kota, negotiated the state’s treaty with the British.
Q2595. In the context of the Human Genome Project, what does SNP stand for?
Explanation
A Single Nucleotide Polymorphism is a variation at a single position in a DNA sequence among individuals. It is the most common type of genetic variation in humans. For example, at a specific location, some individuals may have the base Cytosine, while others have Thymine. SNPs occur throughout the genome and are used as molecular markers to track inheritance and disease.
Q2596. Which Kachwaha ruler committed suicide due to pressure from Maratha invasions and internal conflicts in 1750 CE?
Explanation
Sawai Ishwari Singh of Jaipur faced a tumultuous reign marked by constant Maratha invasions and a bitter succession dispute with his brother, Madho Singh. In 1750, under immense pressure from the Marathas who were demanding heavy tribute and the looming threat of military defeat, he chose to commit suicide by consuming poison. This tragic event highlighted the increasing vulnerability of Rajput states to Maratha military power.
Q2597. The branch of science that evolved alongside the Human Genome Project for storing, retrieving, and analyzing massive biological data is called:
Explanation
Bioinformatics is an interdisciplinary field that developed out of the necessity to handle the massive amounts of data produced by the Human Genome Project. It combines biology, computer science, and statistics to develop tools for storing, retrieving, and analyzing complex biological information. This field is now essential for modern genomics, drug discovery, and personalized medicine, allowing researchers to analyze large-scale genetic datasets.
Q2598. Consider the following statements regarding cultural patronage under Rajput rulers:
I. Maharana Jagat Singh I established the ‘Chiteron Ki Ovari’ (school of art) in Udaipur.
II. Sawai Pratap Singh of Jaipur maintained a guild of 22 scholars known as ‘Gunijan Khana’.
III. Raja Savant Singh of Kishangarh was a patron of the Bani-Thani painting style.
IV. Dingal literature represents the bardic poetry primarily patronized in Western Rajasthan.
Which of the above statement(s) is/are correct?
I. Maharana Jagat Singh I established the ‘Chiteron Ki Ovari’ (school of art) in Udaipur.

IV. Dingal literature represents the bardic poetry primarily patronized in Western Rajasthan.
Which of the above statement(s) is/are correct?
Explanation
Cultural patronage was a hallmark of Rajput royalty. Maharana Jagat Singh I established a major school of art in Udaipur, while Sawai Pratap Singh supported a guild of scholars in Jaipur. Raja Savant Singh of Kishangarh famously patronized the unique Bani-Thani style. Additionally, Dingal literature, the heroic poetry of the bards, was extensively patronized across the states, preserving the martial traditions and genealogies of the various clans.
Q2599. The Sun Temple of Jhalrapatan heavily borrows its architectural elements from which regional style?
Explanation

The temple is famous for its towering shikhara and its intricate carvings, which reflect the sophisticated religious and artistic sensibilities of the medieval Rajput dynasties.
Q2600. Identify the incorrect statement regarding human genome characteristics.
Explanation
Contrary to what might be expected, the function of more than 50% of the genes discovered during the Human Genome Project was unknown at the time of the projects completion. The other statements are correct: Chromosome 1 has the most genes, the Y chromosome has the fewest, and humans are over 99.9% genetically identical at the nucleotide level across all diverse populations.Answer key for these questions
