Synthetic biologist views the genome as the cell's operating system. The hardware, including ribosomes and other parts of the translational and transcriptional apparatus, carry out the instructions contained within this OS. Traditional genetic techniques have allowed us to alter the code and alter the cell in useful and informative ways, but these are limited to manipulation of existing sequence. With a synthetic genome, this limitation disappears. Dramatic alterations of genetic content and arrangement...
