Genome transplantation inbacteria:changing onespecies to another天然完整基因组种间转移:As a step toward propagation ofsynthetic genomes,we completelyreplaced the genome of a bacterialcell with one from another species bytransplanting a whole genome asnaked DNA.Intact genomic DNAfrom Mycoplasma mycoides（蕈状支原体）large colony(LC),virtuallyfree of protein,was transplanted intoMycoplasma capricolum（山羊支原体）cells by polyethylene glycol(PEG)-mediated transformation.Cellsselected for tetracycline resistance,carried by
