  • The layer or membrane around nucleus is called nuclear membrane is semi-permeable in nature which means that only specific molecules and ions can move across it.
  • If the membrane would become permeable, then movement of all types of molecules will occur which will disturb the homeostasis (maintaining balance) of cell and can damage the nucleus.
