A human body contains enough DNA to circle the Earth's Equator for more than 2.5 million times. A long-standing puzzle is to understand the principles which allow cells to both organize their genomes into chromatin fibers in the crowded nuclei, and also to keep the DNA accessible to many protein complexes. Nucleosomes, the basic packaging units of the DNA, allow this millionfold compactification. With nucleosomes covering about three quarters of the DNA, their positions are essential for gene regulation.We study physical models which predict the genome-wide organization of the nucleosomes and also the relevant energies which dictate this organization [1-3]. We present a rigorous statistical mechanics model which is able to explain the recent experimental observations by taking into account nucleosome unwrapping, competition between different DNA-binding proteins, and both the interaction between histones and DNA, and between neighboring histones. We show a series of predictions of our new model, all in agreement with the experimental observations.
