Chromatin in interphase
WebNov 13, 2015 · During interphase, when the cell is carrying out its normal functions, the chromatin is dispersed throughout the nucleus in what appears to be a tangle of fibers. This exposes the euchromatin and … WebWithin an interphase nucleus chromatin is organized into functional territories. Chromatin has been divided into: euchromatin heterochromatin Heterochromatin was defined as a structure that does not alter in its condensation throughout the cell cycle whereas euchromatin is decondensed during interphase. ...

WebDec 5, 2024 · Figure 10.4. 1: The Stages of Interphase and the Cell Cycle: The cell cycle consists of interphase and the mitotic phase. During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. 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 …
