Question:
Which one of the following preceeds reformation of the nuclear envelope during M phase of the cell cycle
Which one of the following preceeds reformation of the nuclear envelope during M phase of the cell cycle
Updated On: Apr 29, 2026
Transcription from chromosomes and reassembly of the nuclear lamina
Formation of the contractile ring and formation of the phragmoplast
Formation of the contractile ring and transcription from chromosomes
Decondensation from chromosomes and reassembly of the nuclear lamina
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
During the M phase, which is also referred to as the mitotic phase and encompasses cell division, the process of re-establishing the nuclear envelope occurs in a stage known as telophase. Specifically, during telophase, the nuclear membrane that had vanished in prophase is reconstructed. However, before this reconstruction takes place, the nucleus undergoes a reorganization process, involving the decondensation of chromosomes and the reassembly of the nuclear lamina.

Concepts Used:
Cells
- A device that converts chemical energy into electrical energy is called an electric cell. To an electric circuit, the battery provides the constant electromotive force.
- Each cell comprises 2 half cells which are connected in series by a conductive electrolyte containing anions and cations:
- One-half cell is made up of electrolyte and a negative electrode called an anion.
- The other half cell is made up of electrolytes and a positive electrode called a cathode.
- Redox reactions take place simultaneously.
- While charging, cations are reduced at the cathode, and anions are oxidized at the anode.
- Electrodes do not join each other as they are electrically connected by the electrolyte.
