WebMitosis is the process of cell division, and is separated into four stages. During prophase, the chromosomes condense and the nuclear envelope dissolves. During metaphase, the chromosomes align at the center of the cell. During anaphase, the sister chromatids are separated and pulled to opposite ends of the cell. WebApr 11, 2024 · During metaphase I, the homologous chromosomes align at the spindle equator with each homologue facing opposite spindle poles. What is metaphase stage? The metaphase stage of meiosis is the stage where the chromosomes/chromatids align at the center or equator of the cell in preparation for separation.
