sentences:  It was accomplished by synthesizing a 600 kbp genome (resembling that of "Mycoplasma genitalium", save the insertion of a few watermarks) via the Gibson Assembly method and Transformation Associated Recombination.Soon after the discovery of restriction endonucleases and ligases, the field of genetics began using these molecular tools to assemble artificial sequences from smaller fragments of synthetic or naturally-occurring DNA.The advantage in using the recombinatory approach as opposed to continual DNA synthesis stems from the inverse relationship that exists between synthetic DNA length and percent purity of that synthetic length.
