I have found this website (i think i mentioned it before) but I really love it. Most textbooks (or i should rephrase this to be, textbooks of my era) don’t think about providing relative “size” and “distribution” to their descriptions biology, cells, organelles, etc. Somehow those relative size tidbits are what help me remember and understand what I read.  So this kind of a chart for me is awesome.  I laud the editors of this book…   I WOULD LOVE TO HAVE a resource where they just had allllll the known protein structures that I could look at and superimpose where they belong over my electron micrographs.  ha ha. Someday, someone will be able to do that.
