Which statement correctly describes the nuclear envelope of a eukaryotic cell?

The nuclear envelope is a single membrane, consisting of a phospholipid bilayer.

Plasmadesmosomes in the nuclear envelope permit the exchange of macromolecules between the nucleus and the cytoplasm.

All of the proteins of the cell are synthesized on ribosomes bound on the nuclear envelope.

The nuclear envelope is continuous with the endoplasmic reticulum.

The outer layer of the nuclear envelope is coated with laminin.

D) The nuclear envelope is continuous with the endoplasmic reticulum.

Explanation:

In eukariotes, the nuclear envelope is a membrane that encloses the nucleus and protects by keeping its contents inside and other substances outside.

This membrane is continuous with the endoplasmic reticulum, connecting the space between the membranes (perinuclear space) and the lumen of the endoplasmic reticulum. This connection permits the movement of different types of molecules across both membranes.
