Researchers can now design and mass-produce genetic material — a technique that helped build the mRNA vaccines.
Today Twist charges nine cents a base pair for DNA, a nearly tenfold decrease from the industry standard a decade ago. As a customer, you can visit the Twist website, upload a spreadsheet with the DNA sequence that you want, select a quantity and pay for it with a credit card. After a few days, the DNA is delivered to your laboratory door. At that point, you can insert the synthetic DNA into cells and get them to begin making — hopefully — the target molecules that the DNA is coded to produce.
