The cell cycle alternates between interphase and mitosis as diagrammed below.
Mitosis has these four phases: prophase, metaphase, anaphase, and telophase.
Prophase ...

Cell cycle progression is controlled by ordered action of cyclin-dependent kinases (CDKs), activated by defined cyclins, appearing for given periods in the cycle.

Cell Cycle
Normal cells grow and divide in an orderly fashion, in accordance with the cell cycle.

Cell cycle: Interphase followed by mitosis
Mitosis is divided into several stages, with the remainder of the cell's growth cycle considered interphase.

cell cycle -- Complete sequence of steps which must be performed by a cell in order to replicate itself, as seen from mitotic event to mitotic event. Most of the cycle consists of a growth period in which the cell takes on mass and replicates its DNA.

Definition: A stage in the cell cycle when a cell doubles its cytoplasm and synthesizes DNA.
Related Resources: Interphase
Interphase is the "holding" stage or the stage between two successive cell divisions.

interphase
A stage of growth in the cell cycle in which metabolism occurs without visible evidence of nuclear division. Interphase is the phase between divisions (meiosis and mitosis).

: One of the first phenomena in the formation of malignancies. It is due to defects in DNA repair and cell cycle controls. This can happen by gain-of-function mutations in proto-oncogenes or loss-of-function mutations in
