As you probably know, a Cell Cycle is a series of events inside of a cell as it divides and grows. A cell spends most of its time in its interphase.
It grows during this period of time, replicates chromosomes, and also prepares for a cell division.
Then the cell leaves the interphase, undergoes mitosis, and then the process is complete!
Sorry if this doesn’t answer your question or if it doesn’t make sense.
