The effect of
Introduction:
There are two phases in the cell cycle: the Interphase and the M phase. Meiosis or mitosis can occur during the M phase. Meiosis is the splitting of the body's germ cells, while mitosis is the splitting of the body's somatic cells. There are three stages in the interphase: Gap 1 or G1., S phase or synthesis, and G2 phase or Gap 2.
