Cell spend most of their time in .
Interphase consists of parts: , , and .
During prophase the centrioles and begins to form. The chromosomes begin to and the begins to break down.
During metaphase the chromosomes up single file in the of the cell. The spindle fibers attach to the region.
During anaphase the spindle fibers begin to pull on the causing the sister chromatids to pull and move to poles of the cell.
During telophase the nuclear membrane begins to again around single , the chromosomes begin to and begins.
During cytokinesis the cell pinches inward, divides into two cells, and the cells begin to enter .
During G1 the cell is and making . During S the chromosomes are being and during G2 the cell continues to and prepares to .
