it must grow and make copies of all the organelles such as mitochondria and ribosomes. The cell must also replicate the chromosomes in the nucleus, then it can divide by mitosis.

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 ...

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 ...

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 ...

Mitosis orchestrates eukaryotic cell division, maintaining genetic fidelity and playing a key role in development, tissue homeostasis, and cancer progression.

Our investigators have also shed light on how changes in the cell cycle — the cycle in which cells grow and divide — push normal cells toward cancer. Having the wrong number of chromosomes is another ...

Meanwhile, the mode of mitosis appears to be intricately connected to the organism's life cycle, which opens up new perspectives on the evolution of cell division mechanisms in eukaryotes.
