the structure that acts as a scaffolding for chromosomal attachment

Starr/Evers Biology Today and Tomorrow with Physiology Starr/Evers Starr/Evers The spindle acts as a scaffolding for the attachment and movement of the chromosomes during later mitotic stages. A secondary interest of his is the development of novel biomedical materials and devices to act as scaffolds for the local delivery of engineered cells and tissue factors. The term S/MAR (scaffold/matrix attachment region), otherwise called SAR (scaffold-attachment region), or MAR (matrix-associated region), are sequences in the DNA of eukaryotic chromosomes where the nuclear matrix attaches.
