There is a lot of organization here, about which I know almost nothing, but it is fun to look at old micrographs and see pattern.  This is only a view of a portion of a nucleus which has some very nicely defined chromatin (right side of the image, overlay is yellow, which measures not that different than a ribosome (middle and left portion of image, pseudocolored purple, and red dot, taken to be about 27nm) of which there are several in the nearby cytoplasm. Bar=approximately 100nm, and the spacing between nuclear chromatin bodies is less than 3/100nm.
