E)the plasma membrane

Question

Quizplus · Accepted Answer

The outer membrane of the nuclear envelope is continuous with the rough endoplasmic reticulum (RER). This is because the RER is studded with ribosomes that are involved in protein synthesis, and proteins that are destined for the nucleus are synthesized on the RER and transported to the nucleus through the nuclear pores. The smooth endoplasmic reticulum (SER) is involved in lipid metabolism and detoxification, and is not directly connected to the nuclear envelope. The Golgi complex is involved in modification and sorting of proteins, and is also not directly connected to the nuclear envelope. The spindle is involved in cell division, and is not part of the nuclear envelope. The plasma membrane is the outermost membrane of the cell, and is not connected to the nuclear envelope.
