Answer : d
Explanation
Using components of the CRISPR system, researchers can add, remove and alter
specific DNA sequences.
The 2020 Nobel Prize in Chemistry has been awarded to Emmanuelle Charpentier of
France and Jennifer A Doudna of the USA for developing CRISPR/Cas9 genetic
scissors.
CRISPR technology replicates a natural defence mechanism in Streptococcus
pyogenes (bacterium) that uses a similar method to protect itself from virus attacks.
A DNA strand, when broken, has a natural tendency to repair itself but the
auto-repair mechanism can lead to the re-growth of a problematic sequence.
Scientists intervene during this auto-repair process by supplying the desired
sequence of genetic codes, which replaces the original sequence.
Q2:
Which of the chemicals mentioned below are banned under the Stockholm Convention?
- Furans
- Chlordane
- DDT
- Hexachlorobenzene
Choose the correct answer using code given below:
- 1 and 2 only

- 3 and 4 only
- 1, 2, 3 and 4
Answer : d
Explanation
India ratified the Stockholm Convention in 2006 as per Article 25(4), which enabled
it to keep itself in a default “opt-out” position such that amendments in various Annexes of the convention cannot be enforced on it unless an instrument of ratification/acceptance/approval or accession is explicitly deposited with UN
depositary.
The convention calls to ban nine of the dirty dozen chemicals (key POPs),
limit the use of DDT to malaria control, and curtail inadvertent production of dioxins and furans.
The convention listed twelve distinct chemicals in three categories: Eight pesticides (aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, mirex and toxaphene)
Two industrial chemicals (poly chlorinated biphenyls and hexachlorobenzene)
Two unintended by-products of many industrial processes involving chlorine
such as waste incineration, chemical and pesticide manufacturing and pulp and paper bleaching (poly chlorinated dibenzo-p-dioxins and dibenzofurans, commonly referred to as dioxins and furans).

- National Company Law Appellate Tribunal has replaced the Competition Appellate Tribunal.

- 1 and 3 only
Answer: d
Explanation:
National Company Law Appellate Tribunal (NCLAT) has replaced the Competition Appellate Tribunal.
It is the Appellate Tribunal to hear and dispose of appeals against any direction issued or decision made or order passed by the Competition Commission of India (CCI).
NCLAT is the Appellate Tribunal for hearing appeals against the orders passed by NCLT(s) under Section 61 of the Insolvency and Bankruptcy Code, 2016 (IBC).
National Company Law Tribunal (NCLT) is a quasi-judicial body in India adjudicating issues concerning companies in the country. The NCLT is the Adjudicating Authority for insolvency proceedings under the Insolvency and Bankruptcy Code, 2016.

- They are the anti-submarine warfare systems developed by DRDO laboratories.
- They are both indigenously built Medium Range air-to-air missiles.
Answer: a
Explanation:
The IMD has begun testing and using ensemble models for weather forecast through its 6.8 peta flops supercomputers “Pratyush” and “Mihir”. They are two of the fastest supercomputers built for weather forecasting in India.
