The main function of the nuclear membrane in a cell is to regulate what goes in and out of the nucleus.

What does the nuclear membrane do?
The nuclear membrane separates a cell's nucleus (the 'brain' of the cell) from the cytoplasm (the rest of the cell, which is composed of fluid cytosol and cellular organelles).

The membrane acts as a double-layered lipid barrier holding the contents of the nucleus, which is why it is also known as the 'nuclear envelope'.

What is the role of the nuclear membrane?
In cell biology, the nuclear membrane performs quite an important job, as it is in charge of protecting the genetic information (DNA) inside the cell nucleus.

The only way that material gets past the cell membrane (in or out) is through nuclear pore complexes, which are selective in what molecules they transport.

The nuclear membrane is also part of the framework of the nucleus.

It provides a 'shell' from which a network of filaments extends deep into the nucleus. Chromosomes attach to these filaments, and this arrangement also provides support and structure for the entire nucleus.

The nuclear membrane surrounds the cell.

It separates the nucleus from everything else. It is actually double (two membranes together) to make it stronger.

Regulates the entry/exit of materials in the nucleus through nuclear pores.
