To accomplish this challenging feat, origins of replication are prepared for 'firing' exclusively in the G1 phase of the cell cycle. After S phase is complete, replication origins do not fire ...

presence of ssDNA signals that "something is wrong" and this also holds true for other phases of the cell cycle. In other words, whether ssDNA is created during replication, or outside of S phase ...

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 cells at that stage}}{\text{total number ...
