What are the three stages of the cell cycle?

G1 phase. Metabolic changes prepare the cell for division. At a certain point - the restriction point - the cell is committed to division and moves into the S phase.S phase. DNA synthesis replicates the genetic material. Each chromosome now consists of two sister chromatids.G2 phase. Metabolic changes assemble the cytoplasmic materials necessary for mitosis and cytokinesis.M phase. A nuclear division (mitosis) followed by a cell division (cytokinesis).

The period between mitotic divisions - that is, G1, S and G2 - is known as interphase.

In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into three periods: interphase, the mitotic (M) phase, and cytokinesis. During interphase, the cell grows, accumulating nutrients needed for mitosis, preparing it for cell division and duplicating its DNA.
