Extensive changes of nucleosome occupancy at the telomeres. Nucleosomal enrichment changes represented by chromosome 3 left and right telomeres and boundary element regions. Lines indicate average log2 ratio of H4 ChIP divided by genomic DNA hybridization intensity over a window of 150 bp: blue = ring, green = trophozoite, red = schizont. Blue (Red) genes are encoded on the top (bottom) strand. The x-axis indicates the base pair position on the chromosome.
