Which of the following accurately pairs the phase of the cell cycle with its primary purpose?
babunello [35]

Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer). </span>
