Synthetic biology is a collection of techniques, and research and business agendas, that includes the construction of DNA sequences that encode protein or RNA molecules which assemble into macromolecu-lar complexes, biochemical circuits and networks with known or novel functions; the substitution of chemically synthesized DNA or DNA analogues for their natural counterparts in order to change cell behavior and/ or produce novel products; and attempts to define and construct basic living systems from minimal sets of molecules.
