"WebbMeiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes.

WebbThe cell goes through 4 steps (prophase, metaphase, anaphase, and telophase.) The cells at the end of the process also have the same amount of chromosomes as the parent cell. At the end, 2 cells are produced. Mitosis is used to make body cells, and occurs in the body. 1 comment. WebbAnswer: Walther fleming coined the term mitosis in the early 1880s. He introduced this term from Greek word for thread, reflecting the shape of mitotic chromosomes. Mitosis is a type of cell division during which one cell gives rise to two genetically identical daughter cells. Q2. Give significance of mitosis.
