Nuclear membrane
membrane part of the nuclear envelope / From Wikipedia, the free encyclopedia
The nuclear membrane (or nuclear envelope) is the membrane inside a cell around the nucleus. It has the genetic material (chromosomes and DNA) and the nucleolus inside it.[1][2][3] The membrane forms a double layer.[4] It is connected to another group of membranes in the cell, the endoplasmic reticulum.

The membranes or envelope is a double lipid bilayer membrane which surrounds the chromosomes and nucleolus in eukaryotic cells.[3]
The nuclear membrane has thousands of nuclear pores. They are large hollow proteins about 100 nm across, with an inner channel about 40 nm wide.[4] They link the inner and outer nuclear membranes.
During cell division, the nuclear membrane breaks down to allow mitosis to take place.
