S. cerevisiae RLS is dictated by the length of the rDNA tandem array located on chromosome XII. As the array becomes shorter, more ERCs accumulate in the aging mother cells, contributing to their senescence. ERCs can reintegrate into the short array while it is destabilized in order to expand again, a process regulated by Sir2 and the RNA polymerase I transcription factor, UAF. Created with BioRender.
