While proposing the double helical structure for DNA, Watson and Crick had immediately proposed a scheme for replication of DNA. The scheme suggested that the two strands would separate and act as a template for the synthesis of new complementary strands. After the completion of replication, each DNA molecule would have one parental and one … Read more Write a short note on DNA replication?

DMH-11 is a Genetically Modified (GM) mustard hybrid. Hybrids are normally obtained by crossing 2 genetically diverse plants from the same species. The 1st-generation offspring resulting from it has higher yields than what either of the parents is individually capable of giving. But there is no natural hybridization system in mustard, unlike in, say, cotton, … Read more DMPQ-Write a short note on GM Mustard.

Adaptive immunity develops when innate immunity is ineffective in eliminating infectious agents and the infection is established. The primary functions of the adaptive immune response are the recognition of specific “non-self” antigens in the presence of “self” antigens; the generation of pathogen-specific immunologic effector pathways that eliminate specific pathogens or pathogen-infected cells; and the development … Read more DMPQ- What do you understand by Adaptive immunity ?

The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle. It is one of the important cycle of atoms … Read more DMPQ: Explain carbon cycle.

To describe the phenomena related to magnets, lines are used to depict the force existing in the area surrounding the magnet. These lines are called the magnetic lines of force. These lines do not exist actually, but are imaginary lines that are used to illustrate and describe the pattern of the magnetic field. As shown … Read more DMPQ- Explain the Magnetic lines of force and their properties.

The phenomenon of technology transfer has existed ever since the beginning of technological progress. Having significantly increased in recent years, it will probably attract the world’s attention for many years to come. Many developing countries now appear to be seeking technological progress through technology transfer to realize development in a much shorter time than that … Read more DMPQ- How India’s technological dependence on foreign countries pose a serious challenge for India security.

Noncommunicable diseases (NCDs), also known as chronic diseases, tend to be of long duration and are the result of a combination of genetic, physiological, environmental and behaviours factors. The main types of NCDs are cardiovascular diseases (like heart attacks and stroke), cancers, chronic respiratory diseases (such as chronic obstructive pulmonary disease and asthma) and diabetes. … Read more DMPQ: India is becoming a hub for non communicable diseases? Suggest the way to deal with the menace of non communicable disease.

VOIP is IP enabled voice calling technology over internet. Example: Skype, Yahoo messenger,MSN messenger.It requires broadband connectivity to make a call along with IP enables  like Computers,Smartphone etc.The voice is converted into digital packets and transmitted to destination over packet switchednetwork. Advantages of VOIP are: Cost of calling is cheaper than normal phone. No need … Read more DMPQ:What is VOIP and write its advantages.

The Mission envisages empowering our national academic and R&D institutions spread over the country by installing a vast supercomputing grid comprising of more than 70 high-performance computing facilities. These supercomputers will also be networked on the National Supercomputing grid over the National Knowledge Network (NKN). The Mission would be implemented and steered jointly by the … Read more DMPQ- Write Short Note on National Supercomputing Mission. (SCIENCE)

Petroleum coke or pet coke, is a solid carbon rich(90% carbon and 3% to 6% sulfur) material derivedfrom oil refining. It is categorized as a “bottom of the barrel” fuel.It is a dirtier alternative to coal and emits 11% moregreenhouse gases than coal and nearly 17 timesmore sulphur than coal. Petcoke is a source of … Read more DMPQ:What is Pet coke?
