Synthetic biology involves the use of engineering principles to design and construct new biological systems, such as microorganisms, to perform specific functions. This can include the production of biofuels, the degradation of pollutants, and the development of new therapeutics. Synthetic biologists use a range of tools, including genetic engineering and gene editing, to design and construct new biological systems. These systems can be designed to be more efficient, more stable, or more productive than natural systems.
