Chromosomal architecture
Chromosomal architecture refers to the three-dimensional organization of chromosomes within a cell’s nucleus. It involves how DNA is folded and arranged, allowing genes to be efficiently accessed or regulated. This structure includes looping, compacting, and compartmentalizing chromosomes so that different regions can interact or stay separate as needed. Proper chromosomal architecture is essential for accurate gene expression, DNA replication, and repair, influencing overall cell function and health. It reflects a dynamic system where the physical arrangement of DNA impacts how genetic information is used and maintained.
