Question

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

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

Answer 1

The correct option is C Decondensation of chromosomes and reassembly of the nuclear lamina

The telophase is the stage of reconstitution of nuclei. Chromosomes uncoil, elongate, lose their stainability and form chromatin fibres. Nucleoplasm and nuclear envelope appear so that two daughter nuclei are formed.

So, the correct answer is option C.
