Micropropagation Ans:  Method of producing thousands of plants through tissue culture is called micropropagation. Each of these plants will be genetically identical to the original plant from which they are grown. They are soma clones. Somatic hybridisation Ans:  In somatic hybridisation cell wall is removed by digesting it with enzyme like pectinase and cellulase. Isolated … Read more DMPQ: Micropropagation, Somatic hybridisation, Single cell protein, Mutation breeding

What is Anti microbial resistance? Ans: Antimicrobial resistance is the ability of a microorganism like bacteria, viruses and some parasites to stop an antimicrobial from working against it . The resistance reduces or eliminates the effectiveness of these drugs, chemicals, or other agents designed to cure or prevent infections. What is VoLTE? Ans: Voice over … Read more DMPQ: What is Anti microbial resistance?

FSOC technology uses beams of light to deliver high speed, high capacity connectivity over a long distance.  The energy beam is sent through clean air or space from the source to the destination, rather than guided through an optical fibre. As long as there is a clear line of sight between the source and the … Read more DMPQ: What is free space optical communication? Write down its advantages ( science)

Q.  Comets Ans:   Comets originate in outer solar system and are formed of cosmic snowballs of frozen gases, rock and dust that orbit the sun. When a comet’s orbit bring it close to the sun ,it heat up and spewn dust and gases into a giant glowing head larger than most planets.   Q.  Dark … Read more DMPQ: Define- Comets, Dark matter, Dark energy and Fundamental particle (Science)

Neutrino Ans:   Neutrinos are one of the fundamental particles which make up the universe and second most abundant particle in the universe after photon. Neutrinos are similar to electron with one crucial difference that they don not carry electric charge.   Indian -based Neutrino observatory Ans:   It is being set up in Bodhi west Hill, … Read more DMPQ: Define all All four questions are from science- Neutrino, Indian -based Neutrino observatory, Goldilock zone, Internet of things

Prahaar –            The Prahaar is India’s latest surface-to-surface missile with a range of 150 kms. The primary objective of the conventionally armed Prahaar missile is to bridge the gap between the unguided Pinaka multi-barrel rocket launcher (ranging 45 kms) and the guided Prithvi missile variants. Stated to be a unique missile, the Prahaar boasts of … Read more DMPQ: Explain: Prahaar,  Sagarika, Shaurya

An electric car is an automobile that uses an electric motor as it’s primary source of propulsion. Electric vehicles (EVs) use electrical energy which is stored in rechargeable batteries. One of the primary benefits of an EV is the lack of tailpipe emissions. The term electric vehicle (EV) is commonly used to refer to three main types of automotive drivetrains. These are Battery … Read more DMPQ: what are the benefits attached in adopting electric vehicles in India?
