Scientists in the US have succeeded in developing the first synthetic living cell. "This is the first time any synthetic DNA has been in complete control of a cell," said Dr Venter.
The researchers constructed a bacterium's "genetic software" and transplanted it into a host cell. The resulting microbe then looked and behaved like the species "dictated" by the synthetic DNA. The advance, published in Science, has been hailed as a scientific landmark, but critics say there are dangers posed by synthetic organisms.
The researchers copied an existing bacterial genome. They sequenced its genetic code and then used "synthesis machines" to chemically construct a copy. Dr Venter told BBC News: "We've now been able to take our synthetic chromosome and transplant it into a recipient cell - a different organism. "As soon as this new software goes into the cell, the cell reads [it] and converts into the species specified in that genetic code."
"These could be used in the future to make the most powerful bioweapons imaginable. The challenge is to eat the fruit without the worm."
