In the mid-1970s a group of scientists asked the National Academy of Sciences to appoint a panel to assess the risks of recombinant DNA technology and the need to control its associated research. Summarize the most important lesson learned from this event
What will be an ideal response?
The most important lesson from these events is that the scientists who developed the methods were the first to call attention to the possible dangers of recombinant DNA research, and they did so only based on its potential for harm. There were no known cases of the release of recombinant DNA–carrying host cells into the environment. Scientists voluntarily shut down their research work until the situation could be assessed properly and objectively. Only when they reached a consensus that there was no danger did their work resume.
