Chromosome territories : ウィキペディア英語版 | Chromosome territories In cell biology, chromosome territories are regions of the nucleus preferentially occupied by particular chromosomes. Interphase chromosomes are long DNA strands that are extensively folded, and are often described as appearing like a bowl of spaghetti. The chromosome territory concept holds that despite this apparent disorder, chromosomes largely occupy defined regions of the nucleus. Most living organisms with a nucleus are thought to have chromosome territories, although the budding yeast saccharomyces cerevisiae is an exception to this. ==Characteristics==
Chromosome territories are spheroid with a diameters on the order of a micrometers. Nuclear compartments devoid of DNA called interchromatin compartments have been reported to tunnel into chromosome territories to facilitate molecular diffusion into the otherwise tightly packed chromosome-occupied regions.
