Is There a Quantum Leap in Technology?
i worked in the area of epigenetics when i was doing my ph dsististed of early two thousands, and we were getting into the idea of studying d an a methelateof these little flags that we find on the sequence of dna. And then our ability to look at methylation marks and see whether things were more methellated or less methelated than we expected is really hard. So there must have been some kind of like quantum leap in the technology between then and now that enables you to do this. I feel like you're almost looking for needles in haystacks when you're talking about finding these tiny fragments of d and a and these little methyll
