* Mitosis: This is the process of cell division where one cell divides into two identical daughter cells.
* G1 phase: This is the first gap phase in the cell cycle. It occurs immediately after mitosis and before the S phase (synthesis). During G1, the cell grows and carries out its normal functions. Crucially, it also checks to make sure conditions are right for cell division to proceed.
* S phase: This is the phase where the cell replicates its DNA, essentially doubling the genetic material.
* G2 phase: This is the second gap phase, where the cell continues to grow and prepares for mitosis.
So, the period between the end of mitosis and the synthesis of more genetic material (S phase) is the G1 phase.
