The phase of mitosis during which the chromosomes align at the middle part of the cell is metaphase.
The phase of mitosis during which the chromosomes align at the middle part of the cell is called metaphase. To remember this, you can break down the word "metaphase" into "meta-" and "-phase." "Meta-" means "middle" or "between," and "-phase" refers to a stage or phase. Therefore, metaphase can be thought of as the phase where the chromosomes are positioned between the two poles of the cell, aligning at the middle part. This is a crucial step in mitosis as it ensures that each daughter cell receives an equal number of chromosomes during cell division.
