Karyokinesis is the process by which chromosomes condense and move during cell division.
染色体运动是细胞分裂过程中染色体聚集和移动的过程。
During mitosis, karyokinesis occurs as the replicated chromosomes align at the metaphase plate.
在有丝分裂中，染色体在中期平版上对齐，此时发生染色体运动。
The first stage of meiosis involves prophase I, which includes karyokinesis and synapsis of homologous chromosomes.
减数分裂的第一阶段包括前期I，包括染色体运动和同源染色体联会。
In eukaryotic cells, cytokinesis usually follows karyokinesis to divide the cytoplasm and form two daughter cells.
在真核细胞中，胞质分裂（cytokinesis）通常紧随染色体运动，形成两个子细胞。
Scientists observe karyokinesis under a microscope to study chromosome organization and behavior in living cells.
科学家在显微镜下观察染色体运动，以研究活细胞中染色体的组织和行为。
Abnormalities in karyokinesis can lead to genetic disorders, such as Down syndrome, resulting from an extra copy of chromosome 21.
染色体运动异常可能导致遗传疾病，如唐氏综合症，由于21号染色体多了一条。
The cell cycle checkpoint mechanism ensures proper completion of karyokinesis before allowing cell division to proceed.
细胞周期检查点机制确保在细胞分裂前完成染色体运动。
Cancer cells often exhibit altered karyokinesis, leading to uncontrolled cell proliferation and tumor growth.
癌细胞常常表现出异常的染色体运动，导致细胞无控制增殖和肿瘤生长。
Researchers use fluorescent tagging to track karyokinesis in real-time, providing insights into its molecular mechanisms.
研究人员使用荧光标记实时追踪染色体运动，揭示其分子机制。
Educational videos often demonstrate karyokinesis with animated illustrations to help students visualize cellular processes.
教育视频通常通过动画插图展示染色体运动，帮助学生形象理解细胞过程。
