There is such a trope - I wouldn't call it accurate. We're learning a lot very fast. But DNA (like most biology) is multi-modal and has roles at many different scales - from the scale of milliseconds to cellular lifetimes, to or

The fun part here is that, technically, once they get a 'good enough' product and workflow up and running, adding/changing/incorporating biological properties is (mostly) just a DNA-based bit-flip away. We at Serotiny ar

A bit of a late reply, sorry, but it's a great question. We found many design decisions we had to confront - more than we expected. The largest two include 1) the decision to use an amino acid sequence as ground truth (and not DNA),
