WebTo begin, let’s explore the different stages of mitosis. Prophase is the first stage of mitosis. In prophase, chromosomes condense and become visible. spindle fibers emerge from the centrosomes. nuclear envelope breaks down. nucleolus disappears. Prometaphase is the second stage of mitosis. In prometaphase, WebApr 13, 2024 · The number of lagging sister chromosomes varied from 1 to 20, and the percentage of PMCs with lagging sister chromosomes was 33.3 ± 8.0% at anaphase II . The percentage of PMCs with lagging homologous or sister chromosomes was significantly higher after treatment at 38 °C for 3 h compared with the control group.
