Cell Cycle As cell passes through its growth cycle, chromatin structure changes. In a non- dividing cell the chromatin is dispersed and fills the entire nucleus. The euchromatin is believed to be primarily in the 30nm chromatin fiber form. These fibers are further organized into large loops. ~ 10% of the euchromatin is in more relaxed (decondensed) state [10 nm chromatin fiber] and this is the DNA that is most transcriptionally active

Although interphase chromain appears to be uniformly distributed, the chromosomes are actually arranged in an organized fashion and divided into discrete functional domains that play an important role in regulating gene expression. The chromosomes are closely associated with the nuclear membrane at many sites. Individual chromosomes occupy distinct territories within the nuclei ....
