Q.1) Consider the following statements regarding Monoclonal Antibodies, seen recently in news:
1. They are man-made protein.
2. They are produced by leucocytes.
Which of the above questions is/are correct?
a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2
Answer : C
Antibodoies are the proteins produced naturally by the immune system that targets a specific foreign object (antigen). They are called monoclonal Antibodies (mAbs) when they are produced by clones derived from a single parent cell.
They are man-made protein that acts like a human antibody in the immune system. They are made by cloning a unique white blood cell or leucocytes.
Q.2) Which of the following correctly defines the term ‘Positive indigenisation list’?
a) Items which can only be purchased from domestic sources
b) These items are to be procured only from within SAARC countries
c) Export ban is imposed on the items in this list
d) Items in this list face zero import duties
The Defence Ministry recently notified the second negative import list — now renamed as the ‘positive indigenisation list’ — of 108 items that can now be only purchased from indigenous sources. The new list takes the total number on the list to 209.
Introduced in August 2020, the negative list essentially means that the Armed Forces—Army, Navy and Air Force—will only procure such items from domestic manufacturers.
The manufacturers could be private sector players or Defence Public Sector Undertakings (DPSUs).
Q.3) The “Three Child Policy”, sometimes seen in the news, was approved recently by which of the following countries?
d. New Zealand
The Republic of China for the first time allowed the couples to have a third child.
This comes as a further relaxation of family planning rules, five years after a “two-child policy” largely failed to boost birth rates.
The Three Child Policy aims to actively address the ageing of population.
The change comes after the recent release of China’s once-in-a-decade population census that painted an alarming picture of declining births.
Forecasts say the population could peak in the next couple of years and most likely by 2025, when India will become the world’s most populous country.
Q.4) Which of the following regions was known as ‘Aparanta’ in ancient times:
c) Northern Circars
Aparanta was a geographical region of ancient India. It corresponded to the northern part of the Konkan region on the western coast of India. It was a bone of contention between the sakas and the satavahanas and is mentioned in Nasik inscription of Gautami Balasri. According to Mahavamsa, the third Buddhist council deputed Great elder Dharmarakshita to do missionary work in Aparanta region.
Q.5) Match the following
Variants of Concern – Country of Origin
Alpha – a. India
Beta – b. Brazil
Gamma – c. South Africa
Delta – d. United Kingdom
Select the correct answer using the codes given below:
a. 1-d; 2-b; 3-c; 4-a
b. 1-b; 2-a; 3-d; 4-c
c. 1-d; 2-c; 3-b; 4-a
d. 1-c; 2-d; 3-b; 4-a
The World Health Organisation (WHO) has recently recommended a set of names to label emerging coronavirus variants that are deemed to be of global concern.
The variant first identified in India, technically known as B.1.617.2, can now be described as ‘Delta’ and the so called ‘UK variant’ as ‘Alpha’ according to a note from the organization.
India’s health ministry had earlier objected to Delta being called the Indian variant.
The existing scientific nomenclature system will continue and the new names would only be to aid public discussion using labels that were “non stigmatizing” to the countries where they were first identified.
Variants of Concern – Country of Origin
Alpha – United Kingdom
Beta – South Africa
Gamma – Brazil
Delta – India
Other variants that too are known to be on the radar but less globally widespread and transmissible, or Variants of Interest, too had Greek names.
A sublineage of the B.1.617 family is B.1.617.1 that was identified in India and now bears the popular label ‘Kappa.’
