DJ and PJ sequence characterization. (A) Major genomic features of the PJ (orange) and DJ (green) contigs. BACs used to construct the contigs are shown as black lines, with BAC names and chromosomal origins indicated (chr17 annotation of AC011841 is incorrect). Satellites are shown in blue, the ACRO138 repeats in red, the large DJ inverted repeat as white arrows, and the rDNA array between the PJ and DJ in gray. (B) Segmental duplication analysis. Lines show segmental duplications from PJ (orange) and DJ (green), indicating the location of the duplicate on the human chromosomes (arranged around the flanking regions). Positions of centromeres (yellow) and telomeres (blue) are indicated. Segmental duplicate length is indicated by line color, as defined below.
