Figure 1.

Genomic location and tandem arrangement of the tRNA cluster. (a) Ideogram of human chromosome 1, indicating the approximate location of the tRNA tandem repeat at 1q23.3. Immediately below is schematic map showing a 206 kb genomic window in the vicinity of the tRNA cluster. The location of the VNTR is indicated in the top section by the black right-facing arrows. Transcripts from the interval are indicated in the second section. Open arrows indicate the genomic coverage of the transcript and direction of transcription. Beneath this is a map showing the location of the indicated repeat types (left side labels). The next section shows a plot of GC percentage across the interval. The final section shows the location of CGI indicated by solid black boxes. (b) Pair-wise alignment of the VNTR and flanking LTR elements using YASS (www.http://bioinfo.lifl.fr/yass/index.php). The locations of the individual VNTR repeat units are represented above and to the left of the plot by black arrows. Gray oval blocks represent the location of LTRs that are excluded from the plot, indicated by gaps in the diagonal line.
