The first living space living creature DNA sequencing and the results of the earth perfect match avbox

For the first time in living space on earth and DNA sequencing results of "perfect match" living space National Aeronautics and Space Administration (NASA) announced on the official website of the 30, the 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 can carry out gene sequencing on 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. Is a test of the experimental accuracy, test MiniION portable DNA sequencer is in normal operation of space – the fact that so far, no problem running, the two sequencing results can be perfectly matched in space and on earth. 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.相关的主题文章:
