The immune system is a complex network of cells and organs that work together to defend against Foreign substances. There are various cells associated with immune system: B-cell: It is a type of white blood cell that makes antibodies. Antibodies are large Y-shaped proteins which bind to specific antigens. This signals the other cells of … Read more DMPQ-Write a short note on cells of Human Immune system.

Cloning is the process of generating a genetically identical copy of a cell or an organism. Cloning happens often in nature—for example, when a cell replicates itself asexually without any genetic alteration or recombination. Prokaryotic organisms (organisms lacking a cell nucleus) such as bacteria create genetically identical duplicates of themselves using binary fission or budding. … Read more DMPQ-. Describe the basic concept of Cloning. Also mention the potential drawbacks of applications of Cloning.

Quantum supremacy refers to quantum computers being able to solve a problem that a classical computer cannot. In the research paper, Google used a 53-qubit processor to generate a sequence of millions of numbers. Though these numbers appeared randomly generated, they conform to an algorithm generated by Google. A classical supercomputer checked some of these … Read more DMPQ-What do you mean by quantum supremacy and how it is going to be beneficial in our quest for prowess in Information and Technology.

India’s Polar Satellite Launch Vehicle (PSLV-C45)  successfully launched EMISAT and 28 international customer satellites from Satish Dhawan Space Centre (SDSC) SHAR in Sriharikota. This flight marked the first mission of PSLV-QL, a new variant of PSLV with four strap-on motors. EMISAT is a satellite built around ISRO’s Mini Satellite-2 bus weighing about 436 kg. The … Read more DMPQ- PSLV-C45

A) Emission trading: Emission trading is a market based approach to control pollution. In this a set of quota is set as limitation on the amount of carbon that can be emitted. If the entity exceeds the quota it has to buy from a seller which has emitted less quantum of carbon than the prescribed … Read more DMPQ: Explain the following terms: ( Envt.) a) Emission trading b) Clean development mechanism c) Joint implementation d) REDD

Home energy monitor is a small hand-held or table-top device with a screen that shows you how much electricity you’re using in your home – some models also allow you to receive the information on your mobile phone, tablet or laptop. Your energy monitor should show you how much energy you’re using, how much it … Read more DMPQ- What is Energy monitor technology?

Chemical weapons are specialised weapons that deliver chemicals that inflict death or injury on humans through chemical actions. They are also called poor man’s bomb because they are relatively cheap and easy to produce. Example of chemical weapons are mustard gas, phosgene, chlorine and nerve agents sarin and VX.           Sarin: The UN had confirmed … Read more DMPQ: What are Chemical weapons? Give some examples.? List down the conventions against the use of chemical weapons.

Yamanaka factors (Oct3/4, Sox2, Klf4, c-Myc) are highly expressed in embryonic stem (ES) cells, and their over-expression can induce pluripotency in both mouse and human somatic cells, indicating that these factors regulate the developmental signaling network necessary for ES cell pluripotency. However, systemic analysis of the signaling pathways regulated by Yamanaka factors has not yet … Read more DMPQ- What are yamanaka genes. Explain their role in our body.

In the 60s and 70s, developed nations like the US, UK, Germany, France and Japan were racing ahead by developing newer technologies and consumer products that were change lifestyles leading to a shift from conservative to indulgent energy consumption. Everything seemed fine until leading oil producing nations, grouped under OPEC and led by the largest … Read more DMPQ- What are the threats for Energy security of India?

(a)LED:  Led is light emitting diode. It is a pn junction diode, which emits light when gets activated. When a suitable energy is applied , electron combines with the electron holes  within the device releasing energy in the form of photons.LED lamps have a lifespan and electrical efficiency which are several times longer than incandescent … Read more Discuss the following a) LED b) Insulated Gate Bipolar transistor c) Properties of tungsten
