During mitosis, the stage at which chromosomes lines up around the equator is?

During mitosis, the stage at which chromosomes line up around the equator is metaphase. Metaphase is the stage in the cell cycle when the chromosomes condense and become visible. They then line up along the equator, or the center of the cell, in preparation for separation and distribution to the two daughter cells. This is a critical stage in the process of cell division and ensures that each daughter cell receives a complete set of chromosomes.
