What stage of meiosis do the centromeres split? - Answers

WebIn mitosis, there are basically 4 phases, namely prophase, metaphase, anaphase, and telophase. During prophase, the chromosomes condense and become visible. The nuclear envelope breaks down and the nucleolus disappears. The centriole moves towards the opposite poles of the cell. During metaphase, the mitotic spindle is formed.
