Science & Technology Current Affairs MCQs
1. As per a recent study, a protein called shugosin gives shape to which structure?
[A] Bone
[B] Muscle
[C] Retina
[D] Chromosome
Show Answer
Correct Answer: D [Chromosome]
Notes:
A new study has found that a protein called shugosin locks the chromosomes into X shapes to give them their structure.
The protein’s function is to maintain the stability of chromosomes during cell division. Also called as SGO1, this protein fits precisely into a sort of keyhole which gives the chromosome its X shape.
2. Spheroidal carbonaceous particle is a component of?
[A] Fly Ash
[B] Saw Dust
[C] Dry Ice
[D] Common Salt
Show Answer
Correct Answer: A [Fly Ash]
Notes:
Spheroidal carbonaceous particle (SCP) is a component of fly ash and is a by-product of industrial high-temperature combustion of coal and fuel-oil.
Recently, researchers from British Antarctic Survey and the University College London, for the first time identified SCP in an Antarctic ice core. The sample dated back to 1936, indicating physical markers of fossil fuel combustion have been trapped in ice layers for decades.
