Question

Equatorial plate is formed during

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

Answer 1

The correct option is C

Metaphase.

The correct option is C:

Explanation of the correct option

Metaphase

1. The cell cycle's metaphase occurs when all of the genetic material is condensed into chromosomes.
2. During the metaphase stage, the equatorial or metaphase plate is formed.
3. The plane is formed in the middle between the poles of a dividing cell during the metaphase stage of mitosis or meiosis, by the migration of chromosomes to the center of the spindle.
   

Explanation of the incorrect options

Option A:

1. The first stage of nuclear division is prophase.
2. It only happens in cells that have gone through interphase.
3. The condensation of chromosomes, the removal of the nucleolus and nuclear membrane, and the development of the spindle machinery are the three fundamental processes of prophase.

Option B:

1. Anaphase is the fourth phase of mitosis, the process by which a parent cell's replicated genetic material is separated into two identical daughter cells from the nucleus.
2. Because to the action of the condensing spindle fibers, the sister chromatids move to opposite poles of the cells during Anaphase.
3. When the pressure is high enough to divide the centromere, the chromatids begin to split. Each chromatid becomes a chromosome at this moment.

Option D:

1. The chromosomes uncoil, two nuclei form, and the cytoplasm divides during telophase.
2. By the end of telophase, the cell has entirely split in two. Telophase is the last stage of cell division in both mitosis and meiosis for eukaryotic cells.

Final Answer: Equatorial plate is formed during Metaphase.
