Stages of the Cell Cycle

Back

The cell cycle includes growth, preparation for division, and division into two daughter cells. In prokaryotic cells, it involves growth, DNA replication, and cell division. In eukaryotic cells, it consists of mitosis and cytokinesis.

Front

Mitosis

Back

Mitosis is the division of a cell's nucleus.

Front

Cytokinesis

Back

Cytokinesis is the division of a cell's cytoplasm.

Front

Interphase

Back

Interphase is the time between cell divisions and includes G₁, S, and G₂ phases.

Front

G₁ Phase

Back

Cells grow and synthesize new proteins and organelles during the G₁ phase.

Front

S Phase

Back

DNA is synthesized and chromosomes are replicated during the S phase.

Front

G₂ Phase

Back

Preparation for mitosis occurs during the G₂ phase.

Eukaryotic Cell Cycle Diagram

Back

The diagram shows the stages of the eukaryotic cell cycle, including G₁, S, G₂, and M phases.

Front

G₂ phase: Preparing for Cell Division

Back

The G₂ phase is the shortest phase of the cell cycle where molecules and cell structures for mitosis are produced. After G₂, the cell enters the M phase for cell division.

Front

M phase: Cell Division

Back

The M phase is quicker than interphase and produces two daughter cells. It includes mitosis and cytokinesis.
