The role of genomic sequence in directing the packaging of eukaryotic genomes into chromatin has been the subject of considerable recent debate. A new paper from Tillo and Hughes shows that the intrinsic thermodynamic preference of a given sequence in the yeast genome for the histone octamer can largely be captured with a simple model, and in fact is mostly explained by %GC. Thus, the rules for predicting nucleosome occupancy from genomic sequence are much less complicated than has been claimed.
