Fig. 3

Nucleosome occupancy, the overall number of nucleosomes bound to DNA at a given locus. In all constructs the unc-54 minimal enhancer locus is present and highlighted in blue with the enhancer center designated as the origin and the x-axis numbering in base pairs. The y-axis is the normalized nucleosome occupancy. A pBYU1, with only the unc-54 minimal enhancer locus. b pBYU9 with the Trifonov sequence loci highlighted in purple. C pBYU14 with the 601 sequence locus in orange. D pBYU18 with the two 601 sequence loci in orange. E pBYU29 with the two 70-bp PRS-322 loci in gray. F pBYU28 with the two 20-bp poly-A runs highlighted in red. G pBYU41 with the forward and reverse 5-bp poly-T runs in light blue. H pBYU44 with the single AAAAAcAAAAA sequence locus in dark blue
