A new technology allows scientists to map, in single cells, the DNA binding sites of transcription factors and other ...

D&D‑seq uses base editing to record DNA–protein interactions in single cells, enabling multiomics mapping of transcription factor and other regulatory proteins.

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...
