Recent experiments have implicated one specific E2F target, CDC6, as a potentially important marker for quiescence ... exclusively in the G1 phase of the cell cycle. After S phase is complete ...

Transcripts upregulated during S phase displayed extensive overlap with genes induced by DNA damage; cell-cycle–regulated transcripts may therefore constitute coherent programs used in response ...

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 ...
