Figure 8.2A scheme for organization of DNA in the nucleus

The nuclear matrix is a fibrous protein-based structure whose precise composition and arrangement in the nucleus has not been described. Euchromatin, predominantly in the form of the 30 nm chromatin fiber (see Figure 2.6) is thought to be attached to the matrix by AT-rich sequences called matrix-associated or scaffold attachment regions (MARs or SARs).
