Question 1 of 5
1. Question
1 pointsConsider the following statements:
- DNA and RNA editing makes permanent changes to a person’s genome.
- RNA editing relies on adenosine deaminase acting on RNA (ADAR) enzymes, which already occur in the human body.
- RNA editing alters the sequence of an RNA from that encoded in the DNA genome.
Which of the above statements are correct?
Correct
Answer: B
Explanation:
- Statement 1 is not correct: RNA editing has some advantages over DNA editing, especially on safety and flexibility. DNA editing makes permanent changes to a person’s genome and sometimes this can lead to irreversible errors. On the other hand, RNA editing makes temporary changes, allowing the effects of the edits to fade over time. In a clinic, this means a doctor can stop the therapy if a problem arises and mitigate long-term risk.
- Statement 2 is correct: RNA editing allows scientists to fix mistakes in the mRNA after the cell has synthesised it but before the cell reads it to make the proteins. One technique involves a group of enzymes called adenosine deaminase acting on RNA (ADAR). Adenosine is one of the building blocks of RNA. ADAR works by converting some of the adenosine blocks in mRNA to another molecule called inosine. RNA editing relies on ADAR enzymes, which already occur in the human body and thus present a lower risk of allergic reactions. This is useful for people who require repeated treatment and/or who have immune sensitivities.
Statement 3 is correct: RNA editing alters the sequence of an RNA from that encoded in the DNA genome. The process has been observed in diverse eukaryotes, in many different RNAs, including messenger RNAs, transfer RNAs, ribosomal RNAs, and micro-RNAs.

Question 2 of 5
2. Question
1 pointsUnder the Pradhan Mantri Matsya Sampada Yojana (PMMSY), where has the Department of Fisheries notified the development of a Tuna Cluster?
Correct
Answer: C
Explanation:
- Option C is correct: The Department of Fisheries, under the Ministry of Fisheries, Animal Husbandry and Dairying has notified the Development of Tuna Cluster in the Andaman and Nicobar Islands under the Pradhan Mantri Matsya Sampada Yojana (PMMSY).
The Andaman and Nicobar Islands offers a prime opportunity for fisheries development, with around 6.0 lakh square km of Exclusive Economic Zone (EEZ) rich in under-exploited sea resources, particularly Tuna and Tuna like high valued species, estimated at 60,000 metric tons.

Question 3 of 5
3. Question
1 pointsConsider the following statements with reference to the Food Corporation of India (FCI):
- It is a statutory body setup under the Food Corporation’s Act 1964.
- One of its objectives is distribution of foodgrains throughout the country for the public distribution system.
- It maintains operational and buffer stocks of foodgrains to ensure national food security.
Which of the above statements are correct?
Correct
Answer: D
Explanation:
- Statement 1 is correct: The Food Corporation of India was setup under the Food Corporation’s Act 1964.
Statements 2 and 3 are correct: in order to fulfill following objectives of the Food Policy: Effective price support operations for safeguarding the interests of the farmers, distribution of foodgrains throughout the country for public distribution system and maintaining satisfactory level of operational and buffer stocks of foodgrains to ensure national food security. Since its inception, FCI has played a significant role in India’s success in transforming the crisis management-oriented food security into a stable security system.

Question 4 of 5
4. Question
1 pointsConsider the following statements with reference to the PM Vidyalaxmi Scheme:
- It provides collateral-free and guarantor-free loans for students admitted to top-ranked institutions.
- Students with a family income up to Rs. 8 lakh are eligible for a 3% interest subsidy on loans during the moratorium period.
- All state government institutions ranked within the top 100 of the NIRF rankings are eligible under this scheme.
How many of the above statements are correct?
Correct
Answer: B
Explanation:
- Statement 1 is correct: The PM Vidyalaxmi Scheme is a new Central Sector scheme that seeks to provide financial support to students so that financial constraints do not prevent anyone from pursuing higher studies. Under the PM Vidyalaxmi scheme, any student who gets admission to a Quality Higher Education Institution (QHEIs) will be eligible to get collateral free and guarantor-free loans from banks and financial institutions to cover the full amount of tuition fees and other expenses related to the course.
- Statement 2 is correct: Students with an annual family income of up to Rs 8 lakh, who are not eligible for other government scholarships or interest subsidies, can receive a 3 per cent interest subsidy on loans up to Rs 10 lakh during the moratorium period. This interest subsidy will be granted to 100,000 students each year, prioritising those from government institutions and those pursuing technical or professional courses.
Statement 3 is not correct: The scheme will be available to India’s top-quality higher educational institutions (HEIs) based on NIRF rankings. Eligible institutions include all government and private HEIs ranked within the top 100 across overall, category-specific, and domain-specific NIRF rankings, as well as state government HEIs ranked between 101-200, and all institutions governed by the central government. This list will be refreshed annually with the latest NIRF rankings.

Question 5 of 5
5. Question
1 pointsWhich one of the following elements naturally occurs as oxides in minerals such as ilmenite and rutile?
Correct
Answer: B
Explanation:
Option B is correct: Titanium is a metal that is the fourth most abundant element in the Earth’s crust, following aluminium, iron, and magnesium. It has similar strength to steel but is about half the weight. It naturally occurs as oxides like ilmenite and rutile, and can exist in stable phases known as α-hcp and β-bcc. Various alloying systems and heat treatments can modify its properties.
