中期, 中期阶段
the stage of mitosis where chromosomes align along the center (equator) of the cell, preparing for their separation into daughter cells
- During metaphase, chromosomes are attached to spindle fibers and align at the cell's equator.
在中期，染色体附着在纺锤丝上并在细胞的赤道处对齐。
- The metaphase plate forms as chromosomes line up in a single row across the center of the cell.
中期板形成时，染色体在细胞中心排成一列。
- Microtubules of the spindle apparatus ensure each chromosome is correctly positioned during metaphase.
纺锤体的微管确保每个染色体在中期正确排列。
- Metaphase ensures that each daughter cell will receive an equal and complete set of chromosomes.
中期确保每个子细胞将获得一组平等且完整的染色体。
- Metaphase marks a critical checkpoint before chromosomes are pulled apart in anaphase during mitosis.
中期标志着在有丝分裂中染色体在后期被拉开之前的一个关键检查点。

中期, 中期阶段
the stage of meiosis where homologous chromosomes align in pairs along the equator of the cell, preparing for their separation into haploid daughter cells
- During metaphase I of meiosis, homologous chromosomes pair up and align at the metaphase plate.
在减数分裂的中期I，同源染色体配对并排列在中期板上。
- The spindle fibers attach to the centromeres of each homologous chromosome pair during metaphase I.
在第一次减数分裂的中期，纺锤丝附着到每对同源染色体的着丝粒上。
- Crossing over between homologous chromosomes occurs during prophase I and influences their alignment in metaphase I.
同源染色体之间的交叉发生在前期I，并影响它们在中期I的对齐。
- Metaphase I ensures that each daughter cell receives a unique combination of chromosomes from each parent.
中期 I确保每个子细胞从每个父母那里获得独特的染色体组合。
- Metaphase II in meiosis follows after the first division, aligning chromatids at the metaphase plate for separation into individual chromosomes.
减数分裂中的中期II紧随第一次分裂之后，将染色单体排列在中期板上，以便分离成单独的染色体。
