Chromatin interphase

WebNational Center for Biotechnology Information WebMar 2, 2024 · Chromosomes occupy distinct territories within interphase nuclei, with little constraints on their shape. Cell division entails the condensation of interphase chromosomes into rod-like structures, compacting chromatin up to 1000-fold. The regularity and ubiquity of this process among eukaryotes likely mean that it is governed by general …
