Atomic force microscopical image of SMC on mica in solution. Image shows raw data, just flattened by the software of the instrument. A) Typical field containing single SMC particles (indicated by arrows) and rosette like structures. B) Zoom of another field showing the rosette structures. C) Speculative model of the formation of the rosettes by SMC dimers, in which SMC head domains form the central part of the structures, and arms extend outwards, in which DNA loops could be trapped.
