The study, published in Proceedings of the National Academy of Sciences reveals that a new method developed by scientists to reduce the threat of bioterrorism using man made biological organisms. This was implemented with modifications in DNA where a set of genetic switches have been developed to control function of genes they need to survive.
This control on genes were developed with addition of mixture of naturally occurring chemicals. These could prevent potential harm from either the theft or misuse of these substances, which are used in biofuels, food, and medicines.
Synthetic biology, a fast developing field providing benefits to society but its potential risks are limiting them on biological designs.
