UPSC Science and Technology Quiz: DNA, Ricin, and Nuclear Fission
Imagine scientists are like detectives solving mysteries about the world.
This quiz is like a test for these detectives.
One mystery is about DNA, which is like a tiny instruction book inside all living things that tells them how to grow.
Scientists figured out what it is and how it looks.
Another mission is going to Mars to study its magnetic field and atmosphere, kind of like checking if Mars has a special shield and how it breathes.
Then there's something called Ricin, which is a very dangerous poison from castor bean plants, like a bad ingredient that shouldn't be in our food.
We also learn about nuclear fission, where a big atom breaks apart to make energy, like breaking a toy to see what's inside and releasing stored power.
Finally, India is getting ready for its first trip to space with astronauts, and they tested a special parachute system to make sure it works safely.
The chemical existence of DNA was discovered by Friedrich Miescher in 1869, not Francis Crick.
NASA's ESCAPADE mission is the first multi-spacecraft orbital science mission to Mars, focusing on its magnetosphere and atmospheric escape.
Ricin is a lethal protein from castor beans and is not used in food or traditional medicine.
Nuclear fission is the splitting of a heavy atomic nucleus into lighter nuclei, releasing a large amount of energy.
ISRO conducted a parachute system deployment test for the Gaganyaan Mission, India's first human spaceflight endeavor.
