Cell Division

Do all cells divide at the same rate?

No, all cells do not divide at the same rate. Cells that require frequent replenishing, such as skin or intestinal cells, may only take roughly twelve hours to complete a cell cycle. Other cells, such as liver cells, remain in a resting state (interphase) for up to a year before undergoing division. Cells such as human brain cells exist for a lifetime in a nondividing state.
