Scientists use bacteria to make a human hormone
Advocates of recombinant DNA research have been insisting that potential benefits from the ingenious new technique of genetic engineering far outweigh any dangers that it could pose. Last week scientists testifying before a Senate subcommittee lent strong support to that argument. They revealed that a group of California researchers has spliced a man-made gene into a bacterium, and then, for the first time, used the altered microbe to make a copy of a mammalian brain hormone that can act biologically in humans. The accomplishment brought closer...
