With reference to ‘Ribonucleic Acid (RNA)’, consider the following statements:
RNA replicates and stores genetic information and it is a blueprint for all genetic information contained within an organism.
RNA forms in the nucleolus.
RNA consists of two strands, arranged in a double helix.
Which of the following statement is/are correct?
Correct
Answer: A Explanation:
Ribonucleic acid (RNA) is a molecule similar to DNA. Unlike DNA, RNA is single-stranded. So, statement 3 is incorrect.
An RNA strand has a backbone made of alternating sugar (ribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), guanine (G), cytosine (C) or uracil (U).
Different types of RNA exist in the cell: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA).
Statement 1 is incorrect: RNA converts the genetic information contained within DNA to a format used to build proteins and then moves it to ribosomal protein factories. More recently, some small RNAs have been found to be involved in regulating gene expression.
Statement 2 is correct: RNA forms in the nucleolus, and then move to specialised regions of the cytoplasm depending on the type of RNA formed. Hence, option A is correct.

With reference to ‘Polar Vortex’, consider the following statements:
A polar vortex is a high-pressure area of the wide expanse of swirling cold air in polar regions.
It always exists near the poles, weakens in summer and strengthens in winter.
The term “vortex” refers to the counter-clockwise flow of air that helps keep the colder air near the poles.
Which of the statements given above is/are correct?
Correct
Answer: B
Explanation:
Statement 1 is incorrect: The polar vortex is a large area of low pressure and cold air surrounding both of the Earth’s poles.
Statement 2 is correct: It ALWAYS exists near the poles, but weakens in summer and strengthens in winter.
Statement 3 is correct: The term “vortex” refers to the counter-clockwise flow of air that helps keep the colder air near the Poles.
Hence, option B is correct.

Consider the following statement about ‘Perseverance Rover Mission’:
Perseverance Rover mission is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet Mars.
Mission seeks signs of ancient life and collects samples of rock and regolith for a possible return to Earth.
Perseverance rover will begin its two-year-long investigation in Hellas Planitia Crater to assess the geology and past climate of the Red planet.
Select the correct answer using the code given below:
Correct
Answer: B
Explanation:
Perseverance Rover Mission –
Statement 1 is correct: Perseverance Rover mission is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet Mars.
Statement 2 is correct: Mission seeks signs of ancient life and collects samples of rock and regolith for a possible return to Earth.
Statement 3 is incorrect: Perseverance rover will begin its two-year-long investigation in Jezero Crater to assess the geology and past climate of the Red planet. Perseverance is also ferrying a helicopter named Ingenuity, the first aircraft to attempt powered, controlled flight on another planet.
Hence, option B is correct.

With respect to the ‘Shukrayaan’, consider the following statements:
Shukrayaan is a mission to Mars to study the planet for more than four years which will be launched either in 2024 or 2026.
It is planned to be launched onboard GSLV Mk II rocket or GSLV Mk III rocket to carry more instruments or fuel.
Indian Space Research Organisation (ISRO) has shortlisted 30 space-based experiment proposals, for its proposed Venus orbiter mission ‘Shukrayaan’.
Which of the statements given above is/are correct?
Correct
Answer: B
Explanation:
Statement 1 is incorrect: Mission Shukrayaan is a mission to study the planet Venus for more than four years to be launched either in 2024 or 2026 during the optimal launch window (Venus is closest to the Earth), which comes about every 19 months.
Statement 2 is correct: It is planned to be launched onboard GSLV Mk II rocket or GSLV Mk III rocket to carry more instruments or fuel.
Statement 3 is incorrect: The Indian Space Research Organisation (ISRO) has short-listed 20 space-based experiment proposals, for its proposed Venus orbiter mission ‘Shukrayaan.
Hence, option B is correct.

With reference to ‘Adaptation Gap’, consider the following statement:
The adaptation Gap is the difference between actually implemented adaptation and a societal set goal.
Adaptation Gap Report is released by United Nations Environment Programme (UNEP).
2021 edition of the report looks at progress in planning for financing and implementing adaptation – with a focus on nature-based solutions.
Which of the statements given above are correct?
Correct
Answer: A
Explanation:
Statement 2 is correct: The United Nations Environment Programme (UNEP) the Adaptation Gap Report. It has recently launched the 5th edition of the report.
Statement 1 is correct: As per the report, the Adaptation Gap is the difference between actually implemented adaptation and a societal set goal.
Statement 3 is incorrect: According to the report, cutting greenhouse gas emissions will reduce the impacts and costs associated with climate change. Achieving the 2°C targets of the Paris Agreement could limit losses in annual growth to up to 1.6 per cent, compared to 2.2 per cent for the 3°C trajectories. The recent edition of the report is Adaptation Gap report 2020 launched in January 2021
