in which mitotic phase does
DNA replication occur?
DNA replication occurs during the S phase of interphase, which is prior to the onset of mitosis.
in which mitotic phase does a cell's chromosomes align at the equator of the cell?
The phase in which a cell's chromosomes align at the equator of the cell is called the metaphase. During metaphase, the duplicated chromosomes, consisting of two sister chromatids, line up along the middle of the cell in a region known as the metaphase plate or equatorial plate. This alignment allows for proper segregation of the chromosomes during cell division.
