What is genetic modification (GM) of crops and how is it done? GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced… Continue reading Everything about GM crops!
Cyber Security and Ethical Hacking Today, technology pervades every nook and cranny of our lives. In a report published in August 2017, nearly 50.7% of the population on Earth is connected to the internet! That is 3.82 billion people! Out of these, nearly 3.03 billion are present on one social media network or the other. Facebook… Continue reading Role Of Technology In Cyber Security & Ethical Hacking
Both PSLV (Polar Satellite Launch Vehicle) and GSLV (Geosynchronous Satellite Launch Vehicle) are the satellite-launch vehicles (rockets) developed by ISRO. PSLV is designed mainly to deliver the “earth-observation” or “remote-sensing” satellites with lift-off mass of up to about 1750 Kg to Sun-Synchronous circular polar orbits of 600-900 Km altitude. The remote sensing satellites orbit the… Continue reading What is the difference between GSLV and PSLV?
