Nuclear Envelope
- The nuclear envelope is a double-membrane boundary that encloses the genetic material of the nucleus.
- The inner nuclear membrane and outer nuclear membrane run roughly parallel to each other around the nucleus.
- The perinuclear cisterna is the narrow space between the inner and outer nuclear membranes.
- Nuclear pores are openings in the nuclear envelope where the inner and outer membranes join.
- Nuclear pores allow selected molecules to move between the nucleus and cytoplasm rather than leaving the nuclear envelope as a sealed barrier.
