Analysis of nucleosome distributions within and around Alu elements. (A) Histogram of the lengths of all Alu elements detected by RepeatMasker. Nucleosome distributions with respect to (B) dimeric Alu elements, (C) FLAMs, and (D) FRAMs are shown. Red and blue lines indicate the distributions in nucleosome DNA tags and random fragments, respectively. Nucleosome positions estimated from the distributions are depicted as pink (within Alu elements) or yellow ovals (around Alu elements).
