Chromosome Territories: The Arrangement of Chromosomes in the Nucleus. Chromosomes occupy specific regions of a nucleus, called “chromosome territories.” These subdomains might be doing much more than just keeping everything organized.
Is chromosome placement in the nucleus random?
Abstract. Chromosomes occupy distinct territories in the interphase cell nucleus. These chromosome territories are non-randomly arranged within the nuclear space.

What is the position of a gene on a chromosome called?

Is DNA in the nucleus?
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
