Distribution of MARs on the ACX and Vha68 gene clusters. A 98 kb region of chromosome 2 L that encompasses four closely related genes (ACXC, ACXB, ACXA and ACXE) and three genes of Vha68 cluster is drawn to scale. Each boxed sub part shows genes, transcripts, paused pol II, MAR peaks, actual sequence tag counts (xy plot), AT rich regions and repeat regions. The tag counts box shows ‘xy’ plot using the total tag count values of two replicates (100 bp window size). A / AT rich and repeat region tracks are reproduced from the UCSC genome browser.
