Web4 okt. 2024 · Metaphase Definition. Metaphase is a stage in eukaryotic cell division in which the chromosomes align on the metaphase plate in the middle of the cell. The stages of prophase and prometaphase come before metaphase. In those stages of cell division, the chromosomes are condensed, the spindle fibers form, and the nuclear envelope is … WebHet belangrijkste verschil tussen profase en metafase is dat chromosomen condenseren tijdens profase, terwijl homologe chromosoomparen zich tijdens metafase in de equatoriale plaat van de cel uitlijnen. Bovendien is profase de eerste fase van nucleaire deling, na interfase, terwijl metafase de tweede fase van nucleaire deling is, na profase.
