During this period, the cell is constantly synthesizing RNA, producing protein and growing in size. This may be a temporary resting period or more permanent. Cells increase in size in Gap 1, produce RNA and synthesize protein. During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. All of the cell's energy is focused on the complex and orderly division into two similar daughter cells.
Mitosis is much shorter than interphase, lasting perhaps only one to two hours.
