Question and Answer
Trang 19Kỳ đầu: Trung tử nhân đôi tiến về hai cực tế bào Nhân
và màng nhân bắt đầu mờ dần Sợi nhiễm sắc co ngắn và hiện rõ.
Kỳ trước: Màng nhân bị tiêu biến, và sợi siêu vi xâm
chiếm không gian tế bào Các sợi siêu vi bám vào các
kinetochore.
Kỳ giữa: Nhiễm sắc thể sắp xếp ở mặt phẳng thoi vô
sắc.
Kỳ sau: Kinetochore bám vào sợi siêu vi, các nhiễm sắc
thể tách ra đi về hai phía cực thoi vô sắc, các sợi siêu vi ngắn dần.
Kỳ cuối: Các nhiễm sắc thể bắt đầu tháo xoắn, nhân và
màng nhân xuất hiện trở lại Quá trình phân bào bắt
đầu, nếp gấp bắt đầu xuất hiện.
