Answer: D

Recently, the Centre through the Agricultural and Processed Food Products Export Development Authority (APEDA) conducted a webinar on “Export Promotion of Tissue Culture Plants’’ such as Foliage, Live Plants, Cut Flowers, and Planting Material” with Department of Biotechnology (DBT) accredited tissue culture laboratories spread across India.

What is Tissue Culture?

• It is the production of new plants from a small piece of plant tissue or cells removed from the growing tips of a plant in a suitable growth medium.
• In this process the growth medium or culture solution is very important as it is used for growing plant tissue because it contains various plant nutrients in the form of ‘jelly’ known as agar and plant hormones which are necessary for the growth of plants.

What are the Applications of Plant Tissue Culture?

• To study the respiration and metabolism of plants.
• For the evaluation of organ functions in plants.
• To study the various plant diseases and work out methods-for their elimination.
• Single cell clones are useful for genetic, morphological and pathological studies.
• Embryonic cell suspensions can be used for large scale clonal propagation.
• Somatic embryos from cell suspensions can be stored for long term in germplasm banks.
• In the production of variant clones with new characteristics, a phenomenon referred to as somaclonal variations.
• Production of haploids (with a single set of chromosomes) for improving crops.
• Mutant cells can be selected from cultures and used for crop improvement.
• Immature embryos can be cultured in vitro to produce hybrids, a process referred to as embryo rescue

Answer: A

The India Meteorological Department (IMD) has predicted the Cyclone Asani to intensify into a ‘severe cyclone’ over Southeast regions of Bay of Bengal.

Key Points:

• The name Cyclone Asani has been given by Sri Lanka. It means ‘wrath’ in Sinhalese.
• Tropical cyclones in the North Indian Ocean region (Bay of Bengal and Arabian Sea) develop during the pre-monsoon (April to June) and post-monsoon (October to December) periods.

Tropical Cyclones

• A tropical cyclone is an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain.
• A characteristic feature of tropical cyclones is the eye, a central region of clear skies, warm temperatures, and low atmospheric pressure.
• Storms of this type are called hurricanes in the North Atlantic and eastern Pacific and typhoons in SouthEast Asia and China. They are called tropical cyclones in the southwest Pacific and Indian Ocean region and Willy-willies in north-western Australia.
• Storms rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
• The conditions favourable for the formation and intensification of tropical storms are:
  1. Large sea surface with temperature higher than 27° C.
  2. Presence of the Coriolis force.
  3. Small variations in the vertical wind speed.
  4. A pre-existing weak low- pressure area or low-level-cyclonic circulation.
  5. Upper divergence above the sea level system.

Answer: D

Recently, Health authorities in the United Kingdom have confirmed a case of monkeypox, a rare viral infection similar to smallpox, in an individual who recently travelled to that country from Nigeria.

Key Points:

About Monkeypox:

• It is a viral zoonotic disease that occurs primarily in tropical rainforest areas of Central and West Africa and is occasionally exported to other regions.
• Monkeypox virus infection has been detected in squirrels, Gambian poached rats, dormice, and some species of monkeys.
• Monkeypox is caused by monkeypox virus, a member of the Orthopoxvirus genus in the family Poxviridae.
• Monkeypox typically presents clinically with fever, rash and swollen lymph nodes.
• Monkeypox virus is mostly transmitted to people from wild animals such as rodents and primates, but human-to-human transmission also occurs.
• The incubation period (time from infection to symptoms) for monkeypox is usually 7-14 days but can range from 5-21 days.
• The clinical presentation of monkeypox resembles that of smallpox, a related orthopoxvirus infection which was declared eradicated worldwide in 1980.
• Vaccinia vaccine used during the smallpox eradication programme was also protective against monkeypox.
• A new third generation vaccinia vaccine has now been approved for prevention of smallpox and
