How is synthetic biology different from existing, related fields like genetic engineering and metabolic engineering?
In some ways, it’s no different. People have been modifying genetic material for much of recorded history via breeding and genetic crosses. With the advent of recombinant DNA technology, more methodical combination of DNA segments became possible. Today, genomic data is available for many of the planet’s organisms AND technologies exist to make the genetic material from scratch. These two technologies of sequencing and synthesis are key enabling technologies of synthetic biology. Traditionally, genetic engineering has been focused on making relatively small changes to biological systems: introducing a new gene into an organism, for instance. An illustrative example is that of improved insulin production through genetically engineering bacterial cells to express the human gene for that protein. By contrast, synthetic biology seeks to start from a “blank slate” and ask, what can we make? Thus, instead of perturbing existing systems and organisms, synthetic biologists attempt to construct
