These are formed by carbon atoms. Allotrope Type Properties Graphite Each … Read more Quick Revision-Allotropes of carbon

Stem cells are special human cells that have the ability to develop into many different cell types, from muscle cells to brain cells. In some cases, they also have the ability to repair damaged tissues.               Stem cells differ from other kinds of cells in the body. Self-renewal: They can divide and renew themselves for … Read more DMPQ- What are stem cells? What are the different types of stem cells and how they are utilised to treat cancer?

A dialysis machine tries to mimic some of the functions of a human kidney. One of the primary jobs of a kidney is to remove urea and certain salts from the blood so they can exit the body in urine. In a dialysis machine, blood from the patient runs through tubes made of a semi-porous … Read more DMPQ-Explain the functioning behind the working of dialysis machine.

It is a technology to bring the changes in the phenotype(the way we appear) by altering the genome. The insertion of foreign gene and thus creating new gene is called recombinant gene. The technology involved in the process is called rDNA technology. Steps in the rDNA technology are: Identification Of donor DNA and Plasmid DNA. … Read more DMPQ: What is recombinant DNA technology? Mention the steps involved in rDNA technology? (Science)

What is catalytic converter? What is its significance. Ans:       Catalytic converters, having expensive metals namely platinum palladium and rhodium as the catalysts, are fitted into automobiles for reducing emission of poisonous gases.

What is its significance.  and What is galvanisation?

The Human genome project was a large, international and multi-institutional effort that took 13 years from 1999 and $2.7 billion to produce a blueprint of the sequence of genes and space between  genes that make up a typical human genome. Following were the observation of HGP (read)- 99% of the total human DNA is junk … Read more What is HGP read? How it is different from HGP write? List down the application of Human genome project?

IndiGen Programme aims to undertake whole genome sequence of thousands of individuals representing diverse ethnic groups from India. It also strives to enable genetic epidemiology and develop public health technologies applications using population genome data. IndiGen  project selected the 1000-odd persons from a pool of about 5,000 and sought to include representatives from every state … Read more DMPQ-Comment on IndiGen.

. Gene therapy is the treatment of disease by replacing, altering, or supplementing a gene that is absent or abnormal and whose absence or abnormality is responsible for the disease. Gene therapy may use the genetic material, DNA, itself as the means of treatment. Most, if not all, diseases have a genetic factor. The genetic … Read more DMPQ- Explain how gene therapy can impact the future of humans.

Vaccine hesitancy reflects concerns about the decision to vaccinate oneself or one’s children. There is a broad range of factors contributing to vaccine hesitancy, including the compulsory nature of vaccines, their coincidental temporal relationships to adverse health outcomes, unfamiliarity with vaccine-preventable diseases, and lack of trust in corporations and public health agencies. Vaccine hesitancy is … Read more DMPQ- WHO listed Vaccine hesitancy as among top 10 threats to global health this year. What do you mean by Vaccine hesitancy.
