Overlooked DNA structures help organize the genome

Overlooked DNA structures help organize the genome Lisa Lock Scientific Editor Robert Egan Associate Editor Northwestern Medicine scientists have discovered that little-studied DNA structures play a central role in organizing the human genome and controlling gene activity, according to a new study published in the Proceedings of the National Academy of Sciences. The study revealed that G-quadruplexes (G4s)—four-stranded DNA structures—directly interact with a key genome-organizing protein...
