Expert Answer:

Dear student,

A double-layered membrane, is the nuclear envelope,that separates contents of the nucleus from the cellular cytoplasm. The envelope is riddled with holes called nuclear pores that allow specific types and sizes of molecules to pass back and forth between the nucleus and the cytoplasm. Hence is the function of the membrane.
