WebbProphase - is the first stage of mitosis where chromosomes condense and become visible, spindle fibers emerge from the centrosomes, nuclear envelope breaks down and nucleolus disappears. Interphase - During interphase, the cell undergoes normal growth processes while also preparing for cell division. WebbDescribe the steps of meiosis I. Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis.
