We have undertaken the purification of ribosomal RNA gene (rDNA) chromatin from the slime mold Physarum polycephalum, in order to study its chromatin structure. In this organism rDNA exists in nucleoli as highly repeated minichromosomes, and one can obtain crude chromatin fractions highly enriched in rDNA from isolated nucleoli. We first developed a nucleolar isolation method utilizing polyamin...

The dynamic organization of chromatin inside the cell nucleus plays a key role in gene regulation and genome replication, as well maintaining integrity. Although static folded state has been extensively studied, dynamical signatures processes such transcription or DNA repair remain an open question. Here, we investigate interphase dynamics human cells response to local damage, specifically, dou...
