From: Precise genome-wide mapping of single nucleosomes and linkers in vivo
Nucleosome spacing and linker lengths are “quantized” even at the gene level. Length distribution of the long DNA fragments (135–175 bp) resulting from H3Q85C cleavages. Examples of yeast genes among the ones containing the highest numbers of reads over their gene bodies show that the distributions of fragment lengths from individual genes (blue curves) resemble the genome-wide distribution (red curve). This indicates that the same gene can have different levels of nucleosome compaction in different cells and at different times
