A
At the cell's poles
B

D
In the nucleolus
Verified step by step guidance1
Understand the context of the question: Metaphase is a stage in mitosis, which is the process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell.
Recall the key events of metaphase: During metaphase, chromosomes are aligned in the middle of the cell to ensure that each daughter cell will receive an identical set of chromosomes.
Identify the structure involved: The spindle fibers, which are part of the cell's cytoskeleton, attach to the centromeres of the chromosomes and help align them.
Determine the location where chromosomes align: In metaphase, chromosomes line up along the metaphase plate, which is an imaginary plane equidistant from the two poles of the cell.
Conclude with the correct answer: The chromosomes line up at the cell's equatorial plane, also known as the metaphase plate, during metaphase.
