Question 1 of 5
Consider the following statements regarding Stem cells.
- Stem cells are unspecialized cells capable of renewing themselves through cell division.
- In many tissues they serve as a sort of internal repair system.
- When a stem cell divides, each new cell will always be a stem cell.
Which of the above statements is/are correct?
CorrectSolution: a)
Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.
Stem cells are distinguished from other cell types by two important characteristics:
- First, they are unspecialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity.
- Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues.

Question 2 of 5
Consider the following statements.
- The process of copying genetic information from one strand of the DNA into RNA is termed as transcription.
- Bacteria contain only mRNA (messenger RNA) and do not have any tRNA (transfer RNA).
Which of the above statements is/are incorrect?
CorrectSolution: b)
The process of copying genetic information from one strand of the DNA into RNA is termed as transcription.
In bacteria, there are three major types of RNAs: mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA). All three RNAs are needed to synthesise a protein in a cell. The mRNA provides the template, tRNA brings aminoacids and reads the genetic code, and rRNAs play structural and catalytic role during translation. There is single DNA-dependent RNA polymerase that catalyses transcription of all types of RNA in bacteria. RNA polymerase binds to promoter and initiates transcription (Initiation).

Question 3 of 5
Consider the following statements regarding Indian Ocean Commission (IOC).
- IOC is the only island driven organisation in the Indian Ocean bringing together the African islands of Comoros, Madagascar, Seychelles and Mauritius.
- United Nations has the observer status for the IOC.
Which of the above statements is/are correct?
CorrectSolution: c)
IOC is the only island driven organisation in the Indian Ocean bringing together the African islands of Comoros, Madagascar, Seychelles and Mauritius, also known as the “Vanilla islands”.
There are also seven observers: China, the European Union, the Organisation internationale de la Francophonie, the Sovereign Order of Malta, India, Japan and the United Nations.

Question 4 of 5
Consider the following statements regarding United Nations General Assembly (UNGA).
- UNGA is the only deliberative, policy-making, and representative organ of the UN.
- The UNGA is the only UN organ wherein all member states have equal representation.
- UNGA is responsible for appointing the non-permanent members to the UN Security Council.
Which of the above statements is/are correct?
CorrectSolution: c)
- The United Nations General Assembly(UNGA) is one of the six principal organs of the United Nations (UN), serving as the main deliberative, policy-making, and representative organ of the UN.
- The UNGA is responsible for the UN budget, appointing the non-permanent members to the Security Council, appointing the Secretary-General of the United Nations, receiving reports from other parts of the UN system, and making recommendations through resolutions.
- It also establishes numerous subsidiary organs to advance or assist in its broad mandate.
- The UNGA is the only UN organ wherein all member states have equal representation.

- APEC projects provide digital skills training for rural communities and help indigenous women export their products abroad.
- Increase energy efficiency and promote sustainable management of forest and marine resources.
- Ensuring disaster resilience and addressing terrorism.
Select the correct answer code:
CorrectSolution: d)
APEC:
It is a regional economic forum established in 1989 to leverage the growing interdependence of the Asia-Pacific.
Aim: to create greater prosperity for the people of the region by promoting balanced, inclusive, sustainable, innovative and secure growth and by accelerating regional economic integration.
Functions:
- APEC works to help all residents of the Asia-Pacific participate in the growing economy. APEC projects provide digital skills training for rural communities and help indigenous women export their products abroad.
- Recognizing the impacts of climate change, APEC members also implement initiatives to increase energy efficiency and promote sustainable management of forest and marine resources.
- The forum adapts to allow members to deal with important new challenges to the region’s economic well-being. This includes ensuring disaster resilience, planning for pandemics, and addressing terrorism.
