DNA vaccines are third generation vaccines, made up of small, circular pieces of bacterial DNA, plasmids. These plasmids are genetically engineered to produce specific antigens from a pathogen. The DNA is injected into the cells of the body where the host cell then interprets the DNA and uses it to synthesize the pathogen’s proteins. An … Read more
Nanoscience and Nanotechnology involves the concept of manipulating the extremely small things at nanoscale. At nanoscale things behave differently and this properties can be utilised across various fields of science like chemistry, biology, medicine, physics and material science. Nanotechnology has various application: Medicine: Nanoparticle can be used as effective drug deliver. This will help to … Read more
The Union Minister of Earth Sciences has recently launched the Gagan Enabled Mariner’s Instrument for Navigation and Information (GEMINI) device. The device is developed for effective dissemination of emergency information and communication on Ocean States Forecast and mapping of Potential Fishing Zones (PFZ) to fishermen. Ocean States Forecast provides the accurate state of the ocean … Read more
According to the several research, it was found that almost two-thirds (64%) of Indians say that they don’t exercise. Interestingly, while nearly half (46%) of consumers say that leading a healthy lifestyle is their top priority, only 37% of them actually exercise. The Fit India Youth Club, a part of the Fit India Movement envisioned … Read more

In vitro fertilisation: In vitro fertilization (IVF) is a complex series of procedures used to help with fertility or prevent genetic problems and assist with the conception of a child. During IVF, mature eggs are collected (retrieved) from ovaries and fertilized by sperm in a lab. Then the fertilized egg (embryo) or eggs (embryos) are transferred … Read more
Coal bed methane is found in the impermeable stone and is trapped in the coal seams. A significant portion of this gas remain as free gas in the joints and fractures of the coal seam. Large quantities of gas are adsorbed on the internal surfaces of the micropores within the coal itself Coal bed methane … Read more
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
Gaseous refinery products include hydrogen, fuel gas, ethane, propane, and butane. Most of the hydrogen is consumed in refinery desulfurization facilities, which remove hydrogen sulfide from the gas stream and then separate that compound into elemental hydrogen and sulfur; small quantities of the hydrogen may be delivered to the refinery fuel system. Refinery fuel gas … Read more
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
