Question

The shortest stage of mitosis often lasting only a few minutes is

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

Hint:

In mitosis, Metaphase is the shortest stage, as chromosomes align at the metaphase plate before separation.

Answer 1

The Correct Option is B

Step 1: Overview of the stages of mitosis.
Mitosis is the process by which a eukaryotic cell divides to form two identical daughter cells. The stages of mitosis include: - Prophase: Chromosomes condense and become visible, and the nuclear membrane begins to dissolve. - Metaphase: Chromosomes align at the metaphase plate. - Anaphase: Chromatids (now chromosomes) are pulled apart toward opposite poles. - Telophase: Chromosomes reach the poles and begin to de-condense, and the nuclear envelope reforms.
Step 2: Identifying the shortest stage.
The shortest stage in mitosis is metaphase, where chromosomes align at the center of the cell. This stage takes only a few minutes. In contrast, prophase and telophase are longer, while anaphase is also relatively brief, but metapahse is still the shortest.
Step 3: Conclusion.
Thus, the shortest stage of mitosis, lasting only a few minutes, is (2) Metaphase.
