Y DAZ BAC clone contigs. Contigs created automatically by the GENTIG program. Copies of DAZ have been assigned the names DAZ1–DAZ4. Recent results suggest that DAZ1 lies closest to the Y centromere and DAZ4 to the telomere (Saxena et al. 2000). Above the contigs is a diagram indicating the location of the DAZ genes within the contigs, the approximate positions of exons within the DAZ genes, and the positions of several restriction motifs that are indicative of specific regions of DAZ (see text). The smaller contig is a combination of two separate contigs created by GENTIG and overlapped as described in text. The arrow below the upper diagram indicates an nbn motif where head-to-head copies of DAZ1 and DAZ2 meet as well as where DAZ4 and DAZ3 meet (lower diagram).
