During metaphase of mitosis, how are the chromosomes arranged in a cell with 18 chromosomes?

• A. Chromosomes are randomly distributed throughout the cell.
• B. Chromosomes are duplicated and separated into two sets.
• C. Chromosomes are condensed and attached to spindle fibers.
• D. Chromosomes are aligned at the cell's equatorial plane.

Answer: (D)

Verified step by step guidance

1. Understand that metaphase is a stage in mitosis where chromosomes are prepared for separation.
2. Recognize that during metaphase, chromosomes are not randomly distributed; they are organized in a specific manner.
3. Recall that chromosomes are condensed and become visible under a microscope during metaphase.
4. Learn that spindle fibers play a crucial role in metaphase by attaching to the chromosomes at their centromeres.
5. Identify that the key arrangement of chromosomes during metaphase is their alignment at the cell's equatorial plane, forming the metaphase plate.
