Nuclear membrane is continuous with:

The correct option is A

Rough Endoplasmic Reticulum

The correct option is A:

Explanation of the correct option:

1. The nuclear membrane surrounds the nucleus.
2. It is continuous with the Rough Endoplasmic Reticulum (RER).
3. RER is connected to the pores of the membrane.
4. It allows the ribosomal subunits to enter RER from the nucleus and help in protein synthesis.

Explanation of the incorrect option(s):

Option B:

Smooth ER does not participate in protein synthesis and it is not continuous with the nuclear membrane.

Option C:

A nuclear membrane is not a continuous cell membrane.

Option D:

1. The Golgi body is not continuous with any organelle.
2. Although ER is continuous with the Golgi body.

Final answer: The nuclear membrane is continuous with the Rough Endoplasmic Reticulum.
