Original Figure Legend: Diagram of the rDNA repeats and surrounding sequence, as assembled for cosmids YSCL9634 (left, Genbank accession no. U53879) and YSCL9362 (right, GenBank accession no. U51921). The numbers shown are the nucleotide coordinates for cosmid YSCL9634. The left rDNA junction (U53879 coordinate 21,811) begins at nucleotide 451,418 of chromosome XII; the right rDNA junction (U53879 coordinate 39,322) is at nucleotide 468,929. The sequence includes 1.92 rDNA repeats, representing the lefmost and rightmost copies in the genome. The remaining 100-200 rDNA repeats in the genome are represented as an insertion at coordinate 460,554. Only one complete 5S rDNA gene (in the left rDNA repeat) is included in this sequence; the 5S rDNA genes in the 3.6-kb repeats are variant genes. The 5S rDNA gene in the last rDNA repeat includes all 5' non-translated sequences (like the normal 5S rDNA in the first repeat), but is missing sequences downstream of the 5S rRNA transcript (like the 5S rDNA genes in the 3.6-kb repeats).

Note from SGD: Since the paper has been published, there has been at least one update to the chromosome XII sequence (insertion of a C at 759511 on 2001-06-12). To be sure of the coordinates listed in the figure above, you can BLAST the GenBank entries to get the current coordinates using the current SGD dataset. (2002-02-28 KD)
