Q5842. Match the vaccine type in List I with its key indigenous Indian example in List II and select the correct answer.
| Vaccine Type | Key Indian Indigenous Example |
|---|---|
| A. Whole-virion Inactivated | i. Corbevax |
| B. DNA Plasmid Vaccine | ii. ZyCoV-D |
| C. mRNA Vaccine | iii. Covaxin |
| D. Protein Subunit Vaccine | iv. GEMCOVAC-19 |
Explanation
India’s COVID-19 vaccine portfolio includes diverse technological platforms. Covaxin is a whole-virion inactivated vaccine, while ZyCoV-D is a DNA plasmid vaccine. GEMCOVAC-19 represents the indigenous mRNA platform, and Corbevax is a protein subunit vaccine. This variety demonstrates the comprehensive technical capability of the Indian biotechnology sector to develop multiple types of vaccines for public health needs and global exports.
Q5843. Match List-I (Architect/Builder) with List-II (Monument) and select the correct answer.
| Architect/Builder | Monument |
|---|---|
| A. Lal Chand Usta | i. Kumbhalgarh Fort |
| B. Mandan | ii. Mehrangarh Fort |
| C. Rao Jodha | iii. Hawa Mahal |
| D. Depa | iv. Ranakpur Jain Temple |
Explanation
The creation of Rajasthan’s most iconic monuments involved the expertise of skilled architects and the vision of royal builders. Lal Chand Usta designed the Hawa Mahal, while Mandan was the mastermind behind Kumbhalgarh. Rao Jodha is credited with founding the Mehrangarh Fort, and Depa served as the chief architect for the intricate Ranakpur Jain Temple, each leaving a lasting architectural legacy.
Q5844. Consider the following statements:
Statement I: mRNA vaccines enter the nucleus of the host cell and integrate with the human genome to confer immunity.
Statement II: Once the viral protein is created by the host cell, the cell breaks down the mRNA instruction and removes it.
Which of the following is correct?
Statement I: mRNA vaccines enter the nucleus of the host cell and integrate with the human genome to confer immunity.
Statement II: Once the viral protein is created by the host cell, the cell breaks down the mRNA instruction and removes it.
Which of the following is correct?
Explanation
mRNA vaccines do not enter the nucleus or integrate with the human genome, so Statement I is incorrect. After the viral protein is made, the cell breaks down the mRNA, so Statement II is correct.
Q5845. Which major structure inside the Chittorgarh Fort is recognized by its distinct blending of Rajput and early pre-Mughal Islamic architectural elements, evident in its domes and arches?
Explanation
The Rana Kumbha Palace within Chittorgarh Fort is an important architectural site that demonstrates the early integration of different styles. Its design includes traditional Rajput features alongside domes and arches that reflect pre-Mughal Islamic influences. This blending of elements highlights the cultural exchanges occurring in the fifteenth century and represents an important transitional phase in the development of medieval Indian palace architecture.
Q5846. Which of the following is the most appropriate description of the primary advantage of mRNA vaccine platforms over traditional vaccine methods?
Explanation
The primary advantage of mRNA technology is its flexibility and speed. Because these vaccines are based on genetic sequences rather than growing live pathogens, scientists can quickly update the code to match new viral variants. This allows for the rapid development of updated boosters. This platform provides a powerful tool for responding to fast-evolving viruses and potential future pandemics more effectively than traditional methods.
Q5847. Consider the following statements about the Dilwara Temples:
I. The ceilings feature extremely intricate, multi-layered pendents resembling lotus drops.
II. The temples were severely damaged by Alauddin Khalji and later restored.
III. They reflect strong patronage from the Chandela rulers.
Which of the above combination of statements is correct?
I. The ceilings feature extremely intricate, multi-layered pendents resembling lotus drops.
II. The temples were severely damaged by Alauddin Khalji and later restored.
III. They reflect strong patronage from the Chandela rulers.
Which of the above combination of statements is correct?
Explanation
The Dilwara Temples are famous for their incredibly detailed marble ceilings, which feature multi-layered, delicate pendents that resemble lotus drops. Historically, these temples faced significant damage during various invasions, including those by Alauddin Khalji, leading to later restoration efforts. Despite the misconception of Chandela influence, the temples were actually patronized by the Solanki and Vaghela dynasties of Gujarat and the local region.
Q5848. Identify the odd one out among the components typically found in a formulated mRNA vaccine.
Explanation
A formulated mRNA vaccine consists of the messenger RNA sequence, lipid nanoparticles for delivery, and various buffers and salts to maintain stability and pH levels. It does not contain any live, weakened, or killed virus particles. This makes the platform inherently safe from the risk of causing the disease it is designed to prevent, as no actual viral components are injected.
Q5849. The ‘Jogi Mahal’, originally built as a royal hunting lodge, is a notable structure associated with the vicinity of which famous fort?
Explanation
The Jogi Mahal is a historic structure located near the entrance of Ranthambore Fort, overlooking the scenic Padam Talao lake. Originally built as a hunting lodge for the Jaipur royal family, it is now used as a rest house. Its peaceful setting and architectural charm make it a notable landmark for visitors exploring the fort and the surrounding national park area.
Q5850. What was the effect of using lyophilization (freeze-drying) technology in the development of India’s indigenous mRNA vaccine?
Explanation
Lyophilization, or freeze-drying, was a critical technological breakthrough for India’s indigenous mRNA vaccine. By converting the vaccine into a stable powder form that can be reconstituted at the time of use, researchers eliminated the need for extreme sub-zero storage. This innovation allows the vaccine to be stored and transported at 2-8°C, making it practical for use in tropical climates and remote regions.Answer key for these questions
