Question

The chromosomes are get aligned at the center of the cell during

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

Answer 1

The correct option is A

Metaphase

The correct option is A:

Explanation of the correct option

1. During metaphase the chromosomes moved to spindle equator and get aligned along the metaphase plate.
2. Spindle fibers are attached to the chromosomes at the centromere region.

Explanation of the incorrect options

Option B:

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

Option C:

During prophase, chromosome shortens and nuclear membrane begins to disintegrate

Option D:

1. During telophase, chromosomes cluster at each spindle pole.
2. Chromosomes uncoil and forms chromatin network.
3. Nuclear envelope reappears.
4. Nucleolus, Golgi complex and endoplasmic reticulum reform.

Final answer:

The chromosomes are get aligned at the center of the cell during Metaphase.
