It is perhaps unexpected that closely related CDK activities can promote events as different as S phase and mitosis. This may mean that in the primeval eukaryote, cell-cycle progression was driven ...

From this understanding, scientists then identified the four characteristic phases of the cell cycle: mitosis (M), gap 1 (G1), DNA synthesis (S), and gap 2 (G2). The study of these phases ...

In mitosis, two cells called daughter cells are produced, each identical to the parent cell. When looking at cells with a microscope, the length of different stages of the cell cycle can be ...
