WebLong answer: Most eukaryotic cells only divide in the presence of mitogens. Mitogens stimulate cell division by increasing the amount of G1 cyclins, which trigger cells to enter Start (i.e., the point in G1 which cells commit to divide). G1 cyclins regulate entry into Start by turning on expression of G1/S and S cyclins.
