A bioinformatic and laboratory investigation into S. cerevisiae's system for the maintenance and homogenization of rDNA. Eliminating mutations and heterogeneity in rDNA repeats is necessary evolutionarily, but harmful to individual organisms--and has been linked to aging-related pathology. We present a forensic investigation of this process using a new whole-genome shotgun dataset, and interpret the results in light of experimental results showing the dynamics of rDNA silencing and recombination in laboratory strains.
