Solution:

The nuclear membrane is bordered by minute pores termed nuclear pores, which are generated by the fusing of two membranes. It’s just a few perforations in the nuclear envelope.

Functions:

• Retains the shape of the nucleus
• Known for preserving the genetic material’s stability by protecting it from cytoplasmic respiratory breakdown.
• Controls the flow of RNA and protein molecules between the nucleus and the cytoplasm in both directions.
