Ví dụ
Metaphase marks a critical checkpoint before chromosomes are pulled apart in anaphase during mitosis.
The metaphase plate forms as chromosomes line up in a single row across the center of the cell.
During metaphase, chromosomes are attached to spindle fibers and align at the cell's equator.
Microtubules of the spindle apparatus ensure each chromosome is correctly positioned during metaphase.
The spindle fibers attach to the centromeres of each homologous chromosome pair during metaphase I.
