Diagram showing the roles of ATP-dependent chromatin remodeling factors lsw2 and Ino80 on the S.cerevisiae rDNA locus. Figure by Yiting Lim The maintenance of ~150 – 200 rDNA repeats within the locus ...

Yeast also accumulate ribosomal DNA (rDNA) circles with age — these are created by homologous recombination at the repetitive rDNA locus and are excised to form extrachromosomal circles that are ...

Yeast TATA-binding protein ... We performed the rDNA locus ChIP experiment similarly, except that HA-TBP was induced at an OD 600 of 0.3 and an OD 600 of 0.45 for the 360 min ...

Geneticists have discovered the key to extending the lifespan of yeast in an experiment that could help ... and his colleagues discovered that the Sir2 had a stabilizing effect on the yeast’s rDNA.
