The Nucleus and its Functional Domains

ID #2418

Does the lamina just hold onto the chromosomes to prevent them from moving out of their domains?


The nuclear lamina is an attachment point for heterochromatin. It may help keep the chromosomes in their territories, but more likely it keeps heterochromatin out of the way since heterochromatin isn't usually being "worked on" by the cellular machinery. The lamina also gives shape to the nucleus and stabilizes the nuclear envelope.
