Question

Which one of the following proceeds reformation of the nuclear envelope during M phase of the cell cycle?

• A. Transcription from chromosomes and reassembly of the nuclear lamina
• B. Formation of the contractile ring and formation of the phragmoplast
• C. Formation of the contractile ring and transcription from chromosome
• D. Decondensation from chromosomes and reassemble of the nuclear lamina

Answer 1

The correct option is D Decondensation from chromosomes and reassemble of the nuclear lamina

M phase is known as mitotic phase and cell division occurs in this phase. The reformation of the nuclear envelope during M-phase of the cell cycle takes place during telophase. The nuclear membrane which disappears during prophase reappears in the telophase. But before it is reformed the nucleus gets reorganised by decondensation from chromosomes and reassemble of the nuclear lamina.
