Potential modes by which chromatin loops are transmitted through mitosis. The looped chromatin structure could persist throughout the cell division cycle. Alternatively, it could dissolve during mitosis but the looping factors might remain bound to chromatin to direct the reformation of the loops upon entry into G1. Finally, chromatin loops could dissolve along with removal of the looping factors. Epigenetic bookmarks (red bars) might facilitate reassembly of transcription factor complexes at the appropriate sites following cell division.
