Which of the following statements about the nuclear envelope is false?
Evgesh-ka [11]

Answer:

b) The nuclear envelope is continuous with the Golgi apparatus.

Explanation:

The nuclear envelope is a nuclear membrane composed of two lipid bilayers: inner and outer membrane and perinuclear space between them. Its outer membrane is continuous with the endoplasmic reticulum. Nuclear pores that are part of this envelope allow the movement of molecules in and from the nucleus (e.g. mRNA formed during transcription should be transported into cytosol through the pores).
