Cell biology: Chromosome territories

Karen J. Meaburn1 & Tom Misteli1

Top

The natural habitat of eukaryotic genomes is the cell nucleus, where each chromosome is confined to a discrete region, referred to as a chromosome territory. This spatial organization is emerging as a crucial aspect of gene regulation and genome stability in health and disease.

What do chromosome territories look like?The word 'chromosome' usually conjures up striking images of the dense, X-shaped entities seen during cell division.
