The nuclear envelope re-forms around each set of chromosomes.

Chromosomes align at the cell's equatorial plane.

Verified step by step guidance

Understand the context of the cell cycle: Metaphase is a stage in mitosis, which is the process of cell division that results in two daughter cells with identical genetic material.
Identify the key events of metaphase: During metaphase, chromosomes align at the cell's equatorial plane, also known as the metaphase plate.
Differentiate metaphase from other stages: In prophase, chromatin condenses into visible chromosomes. In anaphase, sister chromatids are pulled apart to opposite poles. In telophase, the nuclear envelope re-forms around each set of chromosomes.
Focus on the alignment of chromosomes: The alignment of chromosomes at the equatorial plane is crucial for ensuring that each daughter cell receives an identical set of chromosomes.
Conclude with the characteristic feature: The defining characteristic of metaphase is the alignment of chromosomes at the cell's equatorial plane, which prepares them for separation in the next stage, anaphase.
