Mitosis - Definition, Stages, Function and Purpose
WebScience Biology Compare and contrast meiosis and mitosis. Consider the following factors: Number of times DNA is replicated Number of cell divisions Number of daughter cells produced “Ploidy” of daughter cells Type of cells in which the process occurs Number and genetic make-up of chromosomes in parent cell compared to daughter cells. WebMeiosis I. Meiosis 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. reached means in urdu
