WebEach pore is lined by a set of proteins, called the nuclear pore complex, that control what molecules can go in or out.Nuclear Membrane An array of small holes or pores in the nuclear membrane permits the selective passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.Nuclear pore complexes allow … WebThe nuclear envelope acts as a physical barrier, however, cellular function depends on the ability of proteins, RNAs, and ribosomes to travel between the cytoplasm and nucleoplasm. Transport between the compartments occurs through nuclear pores, specialized openings along the surface of the nuclear envelope. shareholders online log in
