Question

The nuclear membrane and nucleolus reappear during

• A. Prophase
• B. Metaphase
• C. Anaphase
• D. Telophase

Answer 1

The correct option is D

Telophase

The correction option is D.

Explanation of the correct option

1. Major changes that happens during telophase are

• Chromosomes cluster at each spindle pole
• Chromosomes uncoil and forms chromatin network
• Nuclear envelope reappears.
• Nucleolus, Golgi complex and endoplasmic reticulum reform.

Explanation of the incorrect options

Option A:

1. During prophase, chromosome shortens nuclear membrane begins to disintegrate.

Option B:

1. During metaphase, chromosomes moved to spindle equator and get aligned along the metaphase plate.

Option C:

1. During anaphase, centromeres split and chromatids separate.
2. Chromatids move to the opposite sides.

Final answer:

The nuclear membrane and nucleolus reappear during telophase.
