If a cell with 6 chromosomes goes through interphase, mitosis, and cytokinesis, how many chromosomes will be in each resulting c
kupik [55]

The chromosomes will be in each resulting cell in two daughter cells.

When a cell with six chromosomes undergoes mitotic cell division the two resulting daughter cells also contain six chromosomes each. In her S phase of mitosis, the genetic material DNA is replicated and each daughter cell receives a copy of all the chromosomes of the parent cell. When mitosis is complete the cell has two sets of 46 chromosomes each surrounded by its own nuclear membrane.

The cell then divides into two parts of her by a process called cytokinesis creating two clones of her of the original cell, each with 46 univalent chromosomes. The copies are pulled apart and each new cell gets an identical copy of each chromosome. This type of cell division is called mitosis and produces cells with a total of 46 chromosomes. It has 46 chromosomes, each made up of two sister chromatids aligned in the metaphase plate.
