Verified step by step guidance

1. Understand that the nucleus of a cell is the organelle where the cell's genetic material, DNA, is organized and stored.
2. Recognize that chromosomes are long strands of DNA that are packaged and organized within the nucleus.
3. Learn that within the nucleus, each chromosome occupies a specific, non-overlapping region known as a 'chromosome territory.'
4. Chromosome territories are important for the regulation of gene expression and the organization of the genome within the nucleus.
5. The concept of chromosome territories helps explain how the spatial arrangement of chromosomes can influence cellular processes such as transcription and replication.
