WebThe centromere is the chromosome region that attaches to a spindle fibre at metaphase of mitosis or meiosis and moves to the spindle pole at anaphase, pulling the rest of the chromosome behind it. It can often be distinguished microscopically at metaphase as a thin constriction in the otherwise thick condensed chromosome, and a point at which the … WebMar 20, 2024 · mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells.
