If I took a swab of the inside of your nose and analysed the DNA, there would be some DNA we would recognise from you, some from bacteria, and some from virus. That would be it, right? There wouldn’t be anything else in your nose? We would be able to classify 100% of the DNA in your nose, wouldn’t we? Wrong! About 20% of the DNA inside your nose is “Biological Dark Matter”. We know how to swab it and test it, but the Gattaca just doesn’t fit anything we know.
WHAT IS IT?
