Synthetic biology means different things to different people. Its leading scientists want to create, characterise and, crucially, standardise individual pieces of DNA. The purpose is to build biological circuits with specific functions, in much the same way that you might arrange components to make an electrical circuit. Others want to produce new versions of genetic code with entirely new letters and entirely unnatural versions of DNA.
The ability to design and build biological systems provides a new way to understand how living things work, yet the field is much more about engineering than it is about pure science. However, many synthetic biologists are seeking to solve problems in more efficient ways than traditional engineering does, with potential applications ranging from fighting pollution and cancer to manufacturing fuel and drugs.
