“僵尸细胞”模糊了生命与非生命的界限

‘Zombie’ cells blur the line between living and non-living things Chris Simms A LIVING, synthetic cell has been made by transplanting a complete genome into a dead bacterium, bringing it back to life. The breakthrough could help synthetic biology live up to its huge, but still distant, promise of engineering organisms to create sustainable fuels, pharmaceuticals and new materials. The Mycoplasma capricolum colony in blue has had a synthetic genome added to it NACYRA ASSAD-GARCIA To get around this issue, John Glass at the J.
