Stem-loop and circle-loop TADs generated by directional pairing of boundary elements have distinct physical and regulatory properties
The chromosomes in multicellular eukaryotes are organized into a series of topologically
independent loops called TADs. In flies, TADs are formed by physical interactions between …
