Location of topologically associated domains (TAD) in the cell nucleus is shown. Chromosome is a structure inside the cell nucleus that carries a large part of the genetic information and is responsible for its storage, transfer and implementation. Chromosome is formed from a very long DNA molecule - a double chain of a plurality of genes. Given that the diameter of the cell nucleus is usually around hundredth of a millimeter or even less, while the total length of DNA constituting human genome is about two meters, it is clear that DNA must be packaged very tightly.
