The rRNA-encoding DNA array has an altered structure in topoisomerase I mutants of Saccharomyces cerevisiae.
All the chromosomes from isogenic TOP1 and top1 strains have similar mobility on pulsed-field gels except for chromosome XII, which fails to migrate into the gels in top1 mutants. Chromosome XII contains the tandem repeats of rRNA-encoding DNA (rDNA). When a segment of chromosome XII containing only...
