n.（细胞分裂）中期

During mitosis, metaphase is when chromosomes align along the equatorial plate, forming a neat row.
在细胞分裂过程中，有丝分裂中期时，染色体沿赤道板整齐排列。
The cells enter metaphase after the completion of prophase, ready for the separation of genetic material.
细胞在前期结束后进入有丝分裂中期，为遗传物质的分离做准备。
In meiosis, metaphase I sees homologous chromosomes pair up and align at the metaphase plate.
在减数分裂中，第一次分裂的中期看到同源染色体配对并排列在赤道板上。
The spindle fibers attach to the centromeres during metaphase, ensuring proper chromosome segregation.
中期时，纺锤丝与着丝粒相连，确保染色体正确分离。
An accurate count of chromosomes can be made during metaphase due to their organized arrangement.
由于染色体的有序排列，在中期可以准确计数染色体。
Scientists study the behavior of chromosomes in metaphase to understand cell division mechanisms better.
科学家通过研究中期染色体的行为来更深入地理解细胞分裂机制。
Metaphase checkpoint ensures that all chromosomes are properly aligned before anaphase begins.
中期检查点确保所有染色体在开始后期之前都已正确排列。
During metaphase II, sister chromatids separate and move towards opposite poles of the cell.
在第二次分裂中期，姐妹染色单体分开并向细胞的两个极移动。
The duration of metaphase varies among different organisms and cell types, affecting overall cell cycle progression.
不同生物和细胞类型的中期持续时间各异，影响整体细胞周期进程。
Abnormalities in metaphase can lead to chromosomal disorders, such as Down syndrome or Turner syndrome.
中期的异常可能导致染色体疾病，如唐氏综合症或特纳综合症。
