Metaphase
01
the stage of mitosis where chromosomes align along the center (equator) of the cell, preparing for their separation into daughter cells
Example
During metaphase, chromosomes are attached to spindle fibers and align at the cell's equator.
The metaphase plate forms as chromosomes line up in a single row across the center of the cell.
Microtubules of the spindle apparatus ensure each chromosome is correctly positioned during metaphase.
02
the stage of meiosis where homologous chromosomes align in pairs along the equator of the cell, preparing for their separation into haploid daughter cells
Example
During metaphase I of meiosis, homologous chromosomes pair up and align at the metaphase plate.
The spindle fibers attach to the centromeres of each homologous chromosome pair during metaphase I.
Crossing over between homologous chromosomes occurs during prophase I and influences their alignment in metaphase I.
