Question

Name the stage of mitosis in which chromosomes get arranged in the equatorial plane.

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

Answer 1

The correct option is C

Metaphase

The correct option is C.

Explanation of the correct option:

1. Mitosis is a process that occurs in all cells in the body except reproductive cells.
2. The number of chromosomes in the daughter cells remains the same (i.e., diploid 2n). Hence, it is called equational division.
3. Mitosis results in the formation of two daughter cells.
4. Prophase, Metaphase, Anaphase, and Telophase are the four stages of mitosis.
5. During metaphase duplicated chromosomes align themselves in the equatorial plane at this stage.

The explanation of the incorrect options:

Option A:

In the anaphase stage, the chromatids separate from each other and move towards opposite poles.
Option B:

The chromosomes get condensed during the prophase stage. They duplicate to produce chromatids.
Option D:

After reaching their respective poles, the chromatids lengthen and resemble chromatin threads at the telophase stage.

Final answer: Metaphase is the stage of mitosis in which chromosomes get arranged in the equatorial plane.
