Double lipid bilayer structure surrounding the chromosomes in eukaryotic cells, part of the endomembrane system.
The nuclear membrane is continuous with the rough endoplasmic reticulum. Also known as the nuclear envelope, the nuclear membrane in combination with the contents it surrounds is known as the cell nucleus.
The nuclear membrane typically disappears during mitosis and meiosis (during prophase) and then reappears prior to cytokinesis (that is, during telophase).
