Here's a breakdown:
* Structure: The nuclear envelope consists of two membranes, an inner membrane and an outer membrane, separated by a space called the perinuclear space.
* Function: The nuclear envelope serves as a barrier between the nucleus and the cytoplasm, protecting the genetic material (DNA) within the nucleus. It also regulates the movement of molecules in and out of the nucleus, controlling what substances have access to the DNA.
* Pores: The nuclear envelope is punctuated by nuclear pores, which are complex structures that act as gateways for the passage of molecules. These pores allow for the selective transport of proteins, RNA, and other molecules between the nucleus and cytoplasm.
