Stages of Interphase

There are three stages of interphase, each phase ends when a cellular checkpoint checks the accuracy of the stage's completion before proceeding to the next. The stages of interphase are:

G1 (Gap 1), in which the cell grows and functions normally. During this time, a lot of protein synthesis occurs and the cell grows - more organelles are produced and increasing the volume of the cytoplasm. If the cell is not to divide again, it will remain in this phase.

Synthesis (S), in which the cell duplicates its DNA (via semi-conservative replication).

G2 (Gap 2), in which the cell resumes its growth in preparation for mitosis.

The duration of time spent in interphase and in each stage of interphase is variable and depends on both the type of cell and the species of organism it belongs to. Some human cells divide every 24 hours; in this case interphase takes about 22 hours.
