Little evidence is found for higher-order organization into 30- or 120-nm fibers, as would be expected from the classic textbook models based on in vitro visualization of non-native chromatin.
Well, chromatin structure might not be everybody’s cup of tea but I once shared an ‘office’ with a couple of French / Polish researchers in Strasbourg. It was all above my head, so I had to make do with the textbooks, and I stuck to my simple cloning of upstream regulatory regions of a retinoid receptor. Now, it appears from this article in Science, the textbooks will need rewriting. Science works.
