Dr Craig Venter says in the Science journal that his team successfully transplanted an entire genome from one bacterium cell to another. Dr Craig Venter says in the journal Science that his team successfully transplanted an entire genome from one bacterium cell to another.
He says he hopes eventually to use the technique to create designer microbes, which could produce artificial fuel or help clean up toxic waste.He says he hopes eventually to use the technique to create designer microbes, which could produce artificial fuel or help clean up toxic waste.

The ultimate plan is to stitch together artificial chromosomes, proteins and other building blocks with the aim of jumpstarting their designer microbe to life. But Dr Venter concedes that this may be a long way away, but he says he has taken an important key step towards that goal.The ultimate plan is to stitch together artificial chromosomes, proteins and other building blocks with the aim of jumpstarting their designer microbe to life.

"What's in this paper is the result of taking a native chromosome from one species," Dr Venter explained."What's in this paper is the result of taking a native chromosome from one species," Dr Venter explained.
"That chromosome was transplanted, inserted through the cell walls, the cell membrane of a second species and, after several days of growth and cell division, the original chromosome in the cell disappears and we have cells containing only the transplanted chromosome.""That chromosome was transplanted, inserted through the cell walls, the cell membrane of a second species and, after several days of growth and cell division, the original chromosome in the cell disappears and we have cells containing only the transplanted chromosome."

"Over the last several years we have had to develop novel techniques and approaches that have not existed before because this field has not existed before," he said."Over the last several years we have had to develop novel techniques and approaches that have not existed before because this field has not existed before," he said.
