There’s still a bet happening. There’s still functionally at the bottom, an actual bet. The thing that I’ve just described is kind of convoluted, but the contract is still a bet. And if you think about futures contracts, which is the analogous thing that they want this to be like, the origin of that has a commodity underneath.

Since the eight reactions were run on fragments of random length, the eight plus and minus reactions collectively produced DNA fragments of all possible lengths.4 The fragments in these eight reactions were separated by size (using gel electrophoresis) and then imaged with autoradiography. Gels were dried and then placed against X-ray film, allowing the radioactive DNA fragments to expose the film and appear as dark bands, which a scientist could then painstakingly translate into the DNA sequence. In 1977, Sanger and colleagues sequenced the first full DNA genome using this method: a small bacterial virus with 5,386 nucleotides in its genome, called ɸX174 or “PhiX.”
“Building is easy now. Knowing what to build, and what not to, is the hard part,” Knecht added.
