How is the nuclear membrane related to the endoplasmic reticulum?
A)Ribosomes that exit the nucleus through the nuclear pore complex attach to ribosome receptor locations on the endoplasmic reticulum,thus providing a means of communication between the two structures.
B)The inner and outer bilayers of the nuclear envelope are separated by a space that is continuous with the space inside the endoplasmic reticulum,thus providing direct contact between the two structures.
C)The nucleolus is present in the nucleus,but communicates directly with the endoplasmic reticulum.
D)The nuclear lamina anchors the endoplasmic reticulum,providing structural support and communication through direct contact.

Question

Quizplus · Accepted Answer

The nuclear membrane is composed of two bilayers, the inner and outer nuclear membranes, which are separated by a space that is continuous with the space inside the endoplasmic reticulum. This provides a direct physical connection between the two structures. Ribosomes that exit the nucleus through the nuclear pore complex also attach to ribosome receptor locations on the endoplasmic reticulum, but this is not the primary reason for the connection between the nuclear membrane and the endoplasmic reticulum. The nucleolus is a structure within the nucleus and does not directly communicate with the endoplasmic reticulum. The nuclear lamina provides structural support to the nucleus, but it does not directly anchor the endoplasmic reticulum.
