The sequence of stages that a dividing eukaryotic cell goes through from the time it is created (by division of a parent cell) to the time it undergoes mitosis. Includes M, G1, S, and G2 phases.

The phase of the cell cycle during which DNA is synthesized and chromosomes are duplicated; the middle part of interphase.

The phase of the cell cycle between DNA synthesis (S phase) and mitosis (M phase); the last part of interphase.

The phase of the cell cycle during which mitosis occurs; includes mitosis and cytokinesis.

The part of the cell cycle during which no cell division occurs. Includes the G1 phase, the S phase, and the G2 phase.

The paired strands of a recently replicated chromosome that has not yet divided.

The region joining two sister chromatids during mitosis and meiosis.

The division of the cytoplasm to form two daughter cells.

A point in the cell cycle that is regulated, and at which the cell cycle can be stopped.

A polypeptide or small protein that is secreted by certain cells and that stimulates other cells to divide or to differentiate.

A protein kinase, activated only when bound to a cyclin, that is involved in the control of the cell cycle.

A complex of two proteins that causes cells to enter the M phase of the cell cycle.

A stage in cell division (mitosis or meiosis) during which chromosomes line up in the middle of the cell.

An array of microtubules formed during cell division that moves chromosomes to opposite sides of the cell.

Nuclear division in eukaryotes producing two daughter nuclei that are genetically identical to the parent.

The phase of the cell cycle that constitutes the first part of interphase before DNA synthesis.
