Responses
The phase of mitosis during which chromosomes align at the middle part of the cell is called the metaphase.

The phase of mitosis during which the chromosomes align at the middle part of the cell is called metaphase.
To understand why chromosomes align at the middle part of the cell during metaphase, let's first review the steps of mitosis:
1. Interphase: The DNA in the cell is replicated.
2. Prophase: The chromosomes condense and become visible. The nuclear membrane breaks down, and spindle fibers start to form.
3. Metaphase: The chromosomes line up at the middle part of the cell, called the metaphase plate.
4. Anaphase: The chromosomes separate and move towards opposite ends of the cell.
5. Telophase: The chromosomes reach the opposite ends of the cell, and the nuclear membrane reforms.
6. Cytokinesis: The cell divides into two daughter cells.
During metaphase, the spindle fibers attach to the centromere region of each chromosome. These spindle fibers help align the chromosomes at the metaphase plate, which is equidistant from the two opposite poles of the cell. This alignment ensures that when the chromosomes separate during anaphase, each daughter cell receives the correct number and type of chromosomes.
Therefore, if you encounter a question asking during which phase of mitosis the chromosomes align at the middle part of the cell, the correct answer would be metaphase.
