The first space DNA sequencing results with the earth’s perfect match (video) shdoclc.dll

The first space DNA sequencing and the results of the earth, "perfect match" NASA astronaut Kate · Rubens for the first time in space using MinION sequencing DNA sequencing. The United States National Aeronautics and Space Administration (NASA) official website announced on August 30th, last weekend, NASA astronaut Rubens Kate · the successful completion of DNA sequencing under microgravity conditions on the international space station, which marks the human has ushered in the new era of gene sequencing of space biology. Rubens, who has just completed the sequencing task, said she and her colleagues on the ground saw the study of genes and systems biology. "We are now opening up a whole new field of Science – space genomics and systems biology." The sequencing of the space is part of the research project on biomolecular sequencing. Sequencing is the use of the British Oxford nano Keyhole Corp MinION sequencing instrument, only the size of the palm, both convenient and fast. The sequencing principle is applied current through the nanopore, while containing liquid samples through the detector, different DNA molecules will cause the current change is not the same, the current change can be identified by the gene sequence. Oxford nano Keyhole Corp provides MinION sequencer, only the size of the palm. Source: NASA official website project will be prepared in advance to mice, viruses and bacteria DNA samples to the space station, conducted by Rubens detection in space, and the ground team members of similar samples were sequenced simultaneously. After comparison, it was found that the two sequencing results in space and on earth could be matched perfectly. Project director NASA ·, microbiologist Sara Wallace said: "Castro; the next step we will take the sequencing process to space, with no sample into space, but directly in the space to prepare samples, and then gene sequencing. Astronauts will not only be able to know the biological sequence, but also in the space to complete the sampling, preparation and sequencing of the entire process, and ultimately identify the unknown alien life." A method of sequencing DNA in space, can be identified by the international space station whether the microorganisms threat the health of astronauts, help scientists understand ground astronauts living environment, timely inform whether they want to do the cleaning or taking antibiotics. Space DNA sequencer is an important tool to protect the health of astronauts who need to stay in space for a long time. In addition, sequencing will become an important tool in other scientific research station, such as direct detection of genetic material or gene expression variation around the track in flight, but do not know the results like before, a few months after returning to earth.
