The cell is in Interphase for most of its life cycle. In Interphase, the cell “prepares” for division by obtaining nutrients and growing, copying its DNA, and replicating its centrioles. The nuclear membrane is still visible.
Chromatin has not yet condensed into chromosomes in this stage.
Spindle fibres from the centrioles attach to the centromeres of the chromosomes
Chromosomes align at the middle of the cell. This organization helps to ensure that in the next phase, when the chromosomes are separated, each new nucleus will receive only one copy of each chromosome.
Citokinesis marks the end of mitosis in the cell cycle. It is where the cell officially splits into two separate cells, called daughter cells. Each daughter cell now has the same number of chromosomes as the original cell before mitosis. The cell splits when a furrow forms that pinches the cell in two.
