Mitotic Metaphase GENE ONTOLOGYGO:0000089 Metaphase is marked by the formation of the metaphase plate. The metaphase plate is formed when the spindle fibers align the chromosomes along the middle of the cell. Such an organization helps to ensure that later, when the chromosomes are separated, each new nucleus that is formed receives one copy of each chromosome. This pathway has not yet been annotated in Reactome. Reactome Database ID Release 4368879 Reactome, http://www.reactome.org ReactomeREACT_434
