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 ...

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 ...

a coauthor and postdoctoral researcher in Reiter’s lab. This sequential expression followed the phases of the traditional cell cycle: G0/G1 (the cell grows larger), S (the cell replicates its DNA), ...

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 ...

A life cycle is the series of stages something passes through during its lifetime ... and finding what you can do to limit their impact on the environment. For example, let’s look at cell phones and ...
