Answer:

At several places nuclear membrane are surrounded by minute pores formed by the fusion of two membranes called as nuclear pore. They are simple perforations on the nuclear envelope.

Functions:

• Retains the shape of the nucleus

• Known to preserve the stability of the genetic material by safeguarding it from respiratory breakdown occurring in the cytoplasm

• Responsible for the movement of RNA and protein molecules in both directions between the nucleus and the cytoplasm.
