Question: Which of the following space agency has successfully performed DNA sequencing in microgravity as part of the Biomolecule Sequencer experiment?
(a) ISRO
(b) NASA
(c) ESA
(d) CNSA
Ans: (b)
Related facts:
- On 30 August 2016 for the first time ever, DNA was successfully sequenced in microgravity as part of the Biomolecule Sequencer experiment.
- It was performed by NASA astronaut Kate Rubins aboard the International Space Station.
- For the first time DNA sequencing is possible in an orbiting spacecraft.
- The Biomolecule Sequencer investigation sent samples of mouse, virus and bacteria DNA to the space station to test a commercially available DNA sequencing device called MinION, developed by Oxford Nanopore Technologies.
- Ability to sequence the DNA of living organisms in space opens a whole new world of scientific and medical possibilities.
- This sequencing could be used to keep astronauts aboard the ISS healthy.
- That could also prevent wasting resources, like antibiotics and disinfectant
- Scientists consider the first DNA sequencing in space as a game changer.
