We built the synthetic genome starting from short pieces of DNA. These were made by chemistry in a test tube, something that would have been prohibitively expensive to do on this scale just a decade or two ago.
Para construir el genoma sintético empezamos por fragmentos cortos de ADN, usando procesos químicos en un tubo de ensayo, algo que habría sido extremadamente costoso de hacer a esta escala hace una o dos décadas.
