A global but stable change in HeLa cell morphology induces reorganization of DNA structural loop domains within the cell nucleus.


DNA of higher eukaryotes is organized in supercoiled loops anchored to a nuclear matrix (NM). The DNA loops are attached to the NM by means of non-coding sequences known as matrix attachment regions (MARs). Attachments to the NM can be subdivided in transient and permanent, the second type is considered to represent the attachments that subdivide the genome… (More)
