NEETBiologyCell Cycle and Cell DivisionMCQ+4 / −1
Which one of the following precedes reformation of the nuclear envelope during M phase of the cell cycle?
  1. A
    Decondensation fromchromosomes. and reassembly of the nuclear lamina
  2. B
    Transcription from chromosomes, and reassembly of the nuclear lamina
  3. C
    Formation of the contractile ring, and formation of the phragmoplast
  4. D
    Formation of the contractile ring, and transcription from chromosomes.
