Multiple choice

Which of the following precedes reformation of the nuclear envelope during M-phase of the cell cycle?

  1. Transcription from chromosomes and reassembly of the nuclear lamina

  2. Decondensation from chromosomes and reassembly of the nuclear lamina

  3. Formation of the contractile ring and transcription from chromosomes

  4. Formation of the contractile ring and formation of the phragmoplast

B Correct answer
Explanation

Nuclear envelope reformation during telophase requires decondensation of chromosomes and reassembly of the nuclear lamina. Transcription from chromosomes resumes after envelope reformation. The contractile ring and phragmoplast are involved in cytokinesis, which occurs after nuclear envelope reformation in animal and plant cells respectively.
