What worries many of the townspeople is Harvard's intention to learn more about DNA, the master molecule of heredity, by inserting segments of DNA from other organisms into E. coli, a common intestinal bacterium often used in genetic research. Some scientists fear that fusion of these DNA segments with E. coli's DNA might create new, lethal microbes against which humans have no immunity. To guard against this and other possible threats, the National Institutes of Health recently issued tough rules to govern such research...
...experiments, which involve transferring DNA into specimens of E coli, a commonly used bacterium, are designed to produce a new species, whose characteristics will be unknown and possibly dangerous...
Researchers plan to use the lab to study the control mechanism of DNA by transplanting genes from warm-blooded animals into E-coli, a common bacteria...
...knows why or how E-coli becomes pathogenic when it does," she said...
...coli strains we will use are not pathogens. They are very weak strains and they don't live well outside human beings," Gilbert said. "They will be growing under conditions which aren't found outside the laboratory...
