How is a normal cell transformed into a cancerous cell? The proteins involved in cell division events no longer appropriately drive progression from one cell cycle stage to the next. Cells that ...

Checkpoints are depicted as thick red bars. The stages of the cell cycle (G1: Gap 1, S: DNA synthesis, G2: Gap 2, and M: mitosis) are indicated. Tumor suppressors act to maintain checkpoints ...

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 ...
