Eukaryogenesis happened abruptly, led by the tension of increasing gene length and the constraints on producing longer ...

The standard eukaryotic cell cycle consists of four phases: G1, S, G2, and M phases. There are three phase transitions in a cell cycle: G1/S to initiate DNA synthesis, G2/M to enter mitosis ...

To maintain ploidy, unidirectional progression through the phases of the cell cycle (G1 → S → G2 → M → G1) is essential. To keep cells from regressing, the transitions of the mitotic cell ...

When looking at cells with a microscope, the length of different stages of the cell cycle can be estimated using the formula: \(\text{Length of time in phase}=\) \(\frac{\text{observed number of ...
