Nucleosomes are an essential component of eukaryotic chromosomes. The impact of nucleosomes is seen not just on processes that directly access the genome such as transcription, but also on an evolutionary timescale. Recent studies in a number of organisms have provided high-resolution maps of nucleosomes throughout the genome. Computational analysis, in conjunction with many other kinds of data, has shed light on several aspects of nucleosome biology. Nucleosomes are positioned by several means, including intrinsic sequence biases, by stacking against a fixed barrier, by DNA-binding proteins and by chromatin remodelers. These studies underscore the critical organizational role of nucleosomes in all eukaryotic genomes. Here, I review recent genomic studies that shed light on the determinants of nucleosome positioning and their impact on the genome.
