Explanation:
Detailed explanation-1: -During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
Detailed explanation-2: -Some cell, like neurons, do not replicate their DNA during interphase, but enter resting phase or quiescence instead. This stage can be seen in the graphic below as the G 0 stage. In this state the cell will exist without dividing until the cell dies.
