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

DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect. Conversely, if … Read more DMPQ- Briefly describe the DNA Fingerprinting. Discuss the important sectors where DNA fingerprinting is being applied.

Applications of tissue culture Rapid Clonal Propagation A clone is a group of individuals or cells derived from a single parent individual or cell through asexual reproduction. All the cells in callus or suspension culture are derived from a single explants by mitotic division. Therefore, all plantlets regenerated from a callus/suspension culture generally have the … Read more DMPQ- Explain the main Applications of tissue culture.

Real time RT-PCR (reverse transcription–polymerase chain reaction) is now one of the most accurate laboratory methods for detecting, tracking, and studying the coronavirus. RT-PCR is a nuclear-derived method for detecting the presence of specific genetic material from any pathogen, including a virus. In order for a virus like the coronavirus to be detected early in … Read more DMPQ- RT PCR method

Polystyrene in Appliances Refrigerators, air conditioners, ovens, microwaves, vacuum cleaners, blenders – these and other appliances often are made with polystyrene (solid and foam) because it is inert (doesn’t react with other materials), cost-effective and long-lasting.     Polystyrene in Automotive Polystyrene (solid and foam) is used to make many car parts, including knobs, instrument … Read more DMPQ- Mention the various applications of Polystyrene.

It is light weighted and is one-third the weight of lead acid batteries. It is nearly 100% efficient in both charging and discharging as compared to lead battery which has 70% efficiency. It completely discharges i.e. 100% as compared to 80% for lead acid. It has life cycle of 5000 times or more compared to … Read more DMPQ: Recently BHEL is negotiating with Libcoin to build India’s first lithium-ion Gigafactory. Discuss the advantages of Lithium ion battery. (Science)

INTEGRATED MISSILE DEVELOPMENT PROGRAMME:   Missile Type Remark Prithvi Short range Surface to Surface ballistic missile – The Prithvi missile is a family of tactical surface-to-surface short-range ballistic missiles (SRBM) and is India’s first indigenously developed ballistic missile. Development of the Prithvi began in 1983, and it was first test-fired on 25 February 1988 from Sriharikota, … Read more Quick Revision- Type of Missile

Air breathing propulsion system: In order to provide thrust by the launch vehicles propellants are used. 70% of the constituent of propellant is oxidiser.  So air breathing propulsion system utilise the atmospheric oxygen as an oxidiser to burn the fuel. Ramjet, Scramjet and Dual Mode Ramjet (DMRJ) are the three concepts of air-breathing engines which … Read more DMPQ: Explain the Concepts of air breathing propulsion and re-usable launch vehicle? How these two technology can be game changer for our quest for space?

Low Pollution: Nuclear power also has a lot fewer greenhouse emissions. It has been determined that the amount of greenhouse gases have decreased by almost half because of the prevalence in the utilization of nuclear power. Nuclear energy has the least effect on nature since it doesn‘t discharge any gasses like methane and carbon dioxide, … Read more DMPQ: Discuss the points in favour of nuclear energy.
