Centromere: tâm động Question and Answer What is condensed genetic material called? Question and Answer What structure guides the movement of chromosomes? Question and Answer During which phase does the number of chromosomes briefly double? Question and Answer Mitosis results in the formation of what? Question and Answer If the chromosomes were not able to reproduce during the S phase of interphase, what would occur? Question and Answer What does a cell after it completes telophase and cytokinesis? Question and Answer Which of the following products is NOT made during interphase? a) RNA b) proteins c) organelles d) spindle fiber Question and Answer What are the two main phases of cell cycle? Question and Answer What is a major event of prophase? Question and Answer What is a major event of metaphase? Question and Answer What is a major event of anaphase? Question and Answer What is the purpose of cytokinesis? Question and Answer Which of the following does NOT occur during mitosis? a) chromosomes condense b) separation of the sister chromatids c) replication of the DNA d) formation of the spindle fibers Question and Answer A particular cell has half as much DNA as some other cells in a mitotically active tissue The cell in question is most likely in a) G1 of interphase b) G2 of interphase c) Metaphase d) Anaphase The cell cycle Kỳ đầu: Trung tử nhân đôi tiến hai cực tế bào Nhân màng nhân bắt đầu mờ dần Sợi nhiễm sắc co ngắn rõ Kỳ trước: Màng nhân bị tiêu biến, sợi siêu vi xâm chiếm không gian tế bào Các sợi siêu vi bám vào kinetochore Kỳ giữa: Nhiễm sắc thể xếp mặt phẳng thoi vô sắc Kỳ sau: Kinetochore bám vào sợi siêu vi, nhiễm sắc thể tách hai phía cực thoi vơ sắc, sợi siêu vi ngắn dần Kỳ cuối: Các nhiễm sắc thể bắt đầu tháo xoắn, nhân màng nhân xuất trở lại Quá trình phân bào bắt đầu, nếp gấp bắt đầu xuất
