These images (taken from salivary polytene nuclei electron micrographs from a publication  by Carla Ritagliati, et al, show me that there is symmetry in the nucleus regardless of what stage of either replication, growth, apoptosis, it is in. And while their publication has to do with totally different topics, i was struck by the duplicate nuclear domains within their images. Because electron microscopy is 2D by inspection of single micrographs of course, this might get translated into a radial symmetry so easily.  Would that I had the equipment and time and funding to figure some of this out. This is from their figure 7 just cut and cropped the images which were obviously bilaterally symmetrical.
