Synthetic genomics is a nascent field of synthetic biology that uses aspects of genetic modification on pre-existing life forms with the intent of producing some product or desired behavior on the part of the life form so created.
Synthetic genomics is unlike genetic modification in the sense that it does not use naturally occurring genes in its life forms. It may make use of custom designed base pair series, though in a more expanded and presently unrealized sense synthetic genomics could utilize genetic codes that are not composed of the four base pairs of DNA that are currently used by life.
The development of synthetic genomics is related to certain recent technical abilities and technologies in the field of genetics. The ability to construct long base pair chains cheaply and accurately on a large scale has allowed researchers to perform experiments on genomes that do not exist in nature. Coupled with the developments in protein folding models and decreasing computational costs the field synthetic genomics is beginning to enter a productive stage of vitality.
Certain companies, such as Synthetic Genomics, have already been formed to take advantage of the many commercial uses of custom designed genomes.
