In a cell cycle of about 24 hours, mitosis will not take more than 1 and 1/2 hours.
The cell cycle is a highly regulated process that consists of interphase, which is further divided into G1, S, and G2 phases, followed by mitosis and cytokinesis. Mitosis, the phase where a cell divides into two identical daughter cells, is a relatively short stage compared to the entirety of the cell cycle.
In a cell cycle of approximately 24 hours, mitosis typically takes up a relatively small portion of the total time. Mitosis itself is a rapid process that includes several sub-stages such as prophase, metaphase, anaphase, and telophase, each with specific events leading to the separation of genetic material into the two daughter cells. While the duration of mitosis can vary among cell types and under different conditions, it generally lasts around one to two hours in mammalian cells.
The majority of the cell cycle is occupied by interphase, where the cell grows, duplicates its DNA, and prepares for cell division. G1 phase involves cell growth and normal cellular functions, S phase is dedicated to DNA synthesis, and G2 phase is focused on final preparations for mitosis. These interphase stages collectively account for a significant portion of the 24-hour cell cycle.
