NEET · Biology · STD 11 - 8. Cell the unit of life
Nuclear envelope is a derivative of
- A microtubules
- B rough endoplasmic reticulum
- C smooth endoplasmic reticulum
- D membrane of Golgi complex.
Answer & Solution
Correct Answer
(B) rough endoplasmic reticulum
Step-by-step Solution
Detailed explanation
(b) : Recent developments have shown that nuclear membrane is derived from rough endoplasmic reticulum. During cell division, nuclear membrane is disintegrated. The nuclear envelope transmembrane proteins are absorbed in the \(RER\). Once the division is completed, \(RER\) reassembles the nuclear envelope.
