The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.
Gear up and Make the Best Use of this initiative.
Do remember that, “the difference between Ordinary and EXTRA-Ordinary is PRACTICE!!”

Question 1 of 5
1. Question
Consider the following statements with respect to ‘Coronal holes’
- These are regions on the sun’s surface where radiation is absorbed from the solar atmosphere
- The holes are a unique phenomenon which appear rarely in the sun’s solar cycle
Select the correct statement(s)
Correct
Solution(d)
Statement Analysis:
Statement 1 Statement 2 Incorrect Incorrect These are regions on the sun’s surface from where fast solar wind gushes out into space. Because they contain little solar material, they have lower temperatures and thus appear much darker than their surroundings. The magnetic field is open to interplanetary space, sending solar material out in a high-speed stream of solar wind. Coronal holes can last between a few weeks to months. The holes are not a unique phenomenon, appearing throughout the sun’s approximately 11-year solar cycle. They can last much longer during solar minimum – a period of time when activity on the Sun is substantially diminished, according to NASA. Context – A phenomenon called “coronal holes” was recently spotted on the sun.

Question 2 of 5
2. Question
With reference to ‘Ballistic Missile Defence (BMD) interceptor AD-1 missile’, consider the following statements
- It is an intermediate-range interceptor missile propelled by a two stage solid motor
- It is designed for both low exo-atmospheric and endo-atmospheric interception
Select the correct statement(s)
Correct
Solution(b)
Statement Analysis:
Statement 1 Statement 2 Incorrect Correct The AD-1 is a long-range interceptor missile propelled by a two-stage solid motor and equipped with indigenously-developed advanced control system, navigation and guidance algorithm to precisely guide the vehicle to the target that move at very high speeds. It is designed for both low exo-atmospheric and endo-atmospheric interception of long-range ballistic missiles as well as aircraft. Context – India successfully tested Ballistic Missile Defence Interceptor capable of neutralising long-range adversary missiles

Question 3 of 5
3. Question
Consider the following statements with respect to ‘Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-cas9 technology’
- CRISPR is a family of DNA sequences found in the genomes of eukaryotic organisms such as animals and plants
- Cas9 enzyme acts as molecular scissors to cut DNA at a location specified by a guide RNA and binds to the target DNA
- CRISPR-Cas9 technology does not work at very low temperatures and disengages from the cleaved-DNA products after the enzyme does the job
Choose the correct answer using the code given below
Correct
Solution(b)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Incorrect Correct Incorrect CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) are short DNA sequences found in the genome of prokaryotic organisms such as bacteria, which are reminders of previous bacteriophage (viruses) attacks that the bacteria successfully defended against. Cas9 enzyme acts as molecular scissors to cut DNA at a location specified by a guide RNA, can bind to and cut the target DNA at very low temperatures. Cas9 (or “CRISPR-associated protein 9”) is an enzyme that uses CRISPR sequences as a guide to recognize and cleave specific strands of DNA that are complementary to the CRISPR sequence. Scientists of Raman Research Institute (RRI) have demonstrated that the Cas9 enzymes strongly bind to the target at very low temperatures and remains bound to the cleaved DNA products even after the enzyme has done its job. Context – Indian scientists have demonstrated for the first time that the associated Cas9 enzyme can bind to and cut the target DNA at very low temperatures.

Question 4 of 5
4. Question
‘Panamaram heronry’ a famous breeding site for herons is located in
Correct
Solution(c)
Panamaram herony is one of the largest mixed species heronry in Kerala and important site for breeding 9 species of water birds, which includes species like black headed-ibis, purple heron, large egret, median egret, little egret, pond heron, night heron, and little cormorant. The heronry is formed on a sandbank on the Panamaram river.
Context – Panamaram heronry, the largest breeding ground of different species of herons in the Malabar region, is set to get a fresh lease of life

Question 5 of 5
5. Question
Consider the following statements regarding ‘Disqualification of elected representatives’
- Tenth Schedule of the Constitution contains detailed provisions aimed to decriminalize electoral politics
- The Election Commission has the power to either remove or reduce the period of a person’s disqualification
- Protection of Civil Rights Act, Customs Act and Income Tax Act are among the category of offences that entail disqualification regardless of the period of punishment.
Choose the correct answer using the code given below
Correct
Solution(a)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Incorrect Correct Incorrect Section 8 of the Representation of the People Act (RPA), 1951, contains provisions to decriminalize electoral politics. The RPA itself provides a remedy through the Election Commission. Under 11 of the Act, the EC may record reasons and either remove, or reduce the period of, a person’s disqualification. The EC exercised this power for Sikkim Chief Minister P.S. Tamang, who served a one-year sentence for corruption, and reduced his disqualification so as to contest a byelection and remain in office Special laws such as the Protection of Civil Rights Act, Customs Act, Unlawful Activities (Prevention) Act, Laws for prevention of Sati, corruption, terrorism and insult to the national flag and national anthem etc, are among the category of offences that entail disqualification regardless of the period of punishment. Income Tax Act doesn’t fall under this ambit Context – Recently two legislators from Uttar Pradesh were convicted of criminal charges and one of them has been disqualified from the state assembly.
