Commercial oligonucleotide synthesis companies will check sequences submitted to them against databases of 'dangerous' or regulated sequences. Flagged sequences won't be synthesized. This was designed to prevent someone from ordering parts of a dangererous virus sequence for assembly of the complete virus.
- the8472 5y agoAre the machines themselves treated like nuclear proliferation/dual use tech?
- Teever 5y agoAnd if they are the next logical question is 'are the machines that make the machines themselves treated like like nuclear proliferation/dual use tech?'
- Teever 5y agoI've assumed as much. I've also wondered if there is some sort ability to order innocuous sequence A from company a, innocuous sequence B from company b and then in the privacy of your own lab do the DNA synthesis equivalent of A xor B to get dangerous sequence C.
- molbioguy 5y agoI think it would be hard to get all the required fragments without raising red flags. There aren't that many synthesis companies and it would take a lot of fragments. Assuming you could get the fragments, its getting easier to assemble (join) them quickly. A 40000 base pair T7 bacteriophage genome was recently assembled from 52 parts in a single reaction (one tube)!
- Teever 5y agoFragment issues aside, the kind of stuff I'm thinking about is somewhat like homomorphic encryption at a genetic/biochemistry level to side step regulations.
