I have a theory as to how it could have coiled up. Assuming that this does not happen in every cell, may be it was the way in which the hydrogen bonds happened to line up. Seeing that it is DNA and all, DNA likes to coil up, thanks to hydrogen bonding. It seems to me that this could very well be the answer. In an addition to my guess, may be the manipulation required in preparing the DNA for EM allowed the hydrogen bonds to line up in just the right way to produce this image. In any case, analyzation aside, it is beautiful and stunningly concentric.
