Using advanced radar imaging that will provide an unprecedented, detailed view of Earth, the NASA-ISRO Synthetic Aperture Radar, or NISAR, satellite is designed to observe and take measurements of some of the planet’s most complex processes. These include ecosystem disturbances, ice-sheet collapse, and natural hazards such as earthquakes, tsunamis, volcanoes and landslides. Data collected from … Read more DMPQ- Write a short note on NISAR.

Totipotent cells: Stem cells are characterized according to their degree of potency, which refers to their varying ability to differentiate into different cell types. Totipotent cells are the most potent of all stem cells, and defining them is important for research and the field of regenerative medicine.A totipotent cell is a single cell that can give … Read more DMPQ- Difference between totipotent and pluripotent Cells

In the strictest sense, a super earth is just a planet with more mass than Earth, but less than a larger planet like Uranus or Neptune. So, super earths made of rock and metal, or even ice and gas. These planets could have oceans and atmospheres, or made of nothing but hydrogen and helium. The … Read more DMPQ- What do you understand by the term Super Earth?

PCR (polymerase chain reaction) is a method to analyze a short sequence of DNA (or RNA) even in samples containing only minute quantities of DNA or RNA. PCR is used to reproduce (amplify) selected sections of DNA or RNA. Previously, amplification of DNA involved cloning the segments of interest into vectors for expression in bacteria, … Read more DMPQ: Explain PCR Process and the application of it to diagnose the COVID-19
