Question

Is the nuclear envelope a derivative of the endoplasmic reticulum?

Answer 1

Nuclear envelope:

1. The nucleus envelope is a double membrane covering that surrounds the nucleus.
2. Due to its porous nature, it allows the movement of specific molecules, such as nucleic acids and proteins, between the nucleus and the cytoplasm.
3. The nuclear envelope is a derivative of the endoplasmic reticulum, as it is produced by rough endoplasmic reticulum (RER) in telophase.
4. It consists of a double lipid bilayer membrane- the inner nuclear membrane and the outer nuclear membrane.
