A hidden DNA code


Not only does DNA encode genes, it also contains the information that directs nucleosomes, the packing unit of DNA in eukaryotes, to specific locations. Thijn van der Heijden en John van Noort employed a statistical physics model to uncover this second layer of information. By precise positioning nucleosomes with respect to genes, eukaryotic cells can hardwire the relative activity of their genome.
