WebThe cell cycle shows interphase (I) and mitosis (M). Interphase consists of G1, DNA synthesis (DNA), and G2 phases. Cells that stop dividing exit the G1 phase of the cell cycle into a so-called G0 state. Mitosis results in two new cells with identical DNA to each other, where the entire cell cycle begins again. [Image credit: Wikipedia.] WebMar 1, 2024 · Mitosis differs from meiosis in that meiosis is the production of gametes, or sex cells, which will allow for genetic recombination in sexual organisms. However, without mitosis, the embryos formed will never grow to become organisms. Mitosis is preceded by DNA replication, to form two diploid sets of chromosomes. Mitosis has five phases.
