Chapter 3 The Nucleus
Nuclear envelope
2 concentric membranes separated by narrow
perinuclear space which is - with the outer membrane
of envelope- are continuous with RER.
Nuclear lamina is associated with inner membrane
and stabilizes the nuclear envelope and is formed of
intermediate filament proteins called lamins.
Inner and outer membrane is bridged by nuclear pore complexes.
Nucleoporins regulate diffusion of macromolecules between nucleus and cytoplasm
Energy for transport through envelope is derived from GTP.
Liver cells have large, central nuclei
