The nuclear membrane is selectively permeable, True/False.

Hint: One can say that the nucleus is the controlling center of the eukaryotic cell. Every eukaryotic cell has one nucleus or uninucleate each. However, some have many nuclei or multinucleate, whereas specific cells such as mature mammalian red blood cells, do not have it. Almost all, but Paramecia have two nuclei, such as a macronucleus and a micronucleus. The nucleus contains most of the genetic materials of the cell.

Complete answer: The Nuclear membrane is selectively permeable, and the nuclear membrane has nuclear pores. This permeability of the nuclear membrane helps to restrict what enters and leaves the nucleus. Nucleus and chromatin are covered and protected by the Nuclear membrane. The nuclear membrane works very similarly to the cell membrane, and it also works as the same function as the cell membrane, except that it is applying processes to the cell Nucleus.
So, the statement is true.

Note:
Each nuclear pore consists of a large multiprotein complex and is termed as a nuclear pore complex. Each atomic pore complex consists of multiple copies of roughly 30 different proteins. The proteins that make up the nuclear pore complex are known as nucleoproteins. The typical mammalian nucleus cell contains more than about 3000 to 4000 pores. Each nuclear pore complex is a cylindrical structure with octagonal symmetry. The nuclear envelope contains nuclear pores that help to transport macromolecules between the cytoplasm and nucleus.
