What is the primary function of the nuclear membrane?

The primary function of the nuclear membrane is to contain nuclear pores for communication between the nucleus and cytoplasm. The nuclear membrane, or nuclear envelope, is a double lipid bilayer that surrounds the nucleus and serves as a barrier that separates the contents of the nucleus from the cytoplasm. The presence of nuclear pores is crucial because they act as selective gateways, allowing specific molecules such as RNA and proteins to enter and exit the nucleus. This selective transport is essential for processes like gene expression and regulating cellular activities.

The nuclear membrane's structure also helps maintain the integrity of the genetic material within the nucleus while facilitating communication with the rest of the cell, which is vital for maintaining cellular function and coordination.
