Answer: chromosomes line up at the spindle of equator during Metaphase phase of mitosis.
Explanation:
Mitosis is a process of cell division that take placemajorly in eukaryotic cells where a parent cell divide to give to identical daughter cells. Mitosis is divided into five stages which are prophase, prometaphase, metaphase, anaphase and telophase.
During prophase the sisters chromatics are joined together at the central point called centromere.
In prometaphase the nuclear envelope that house the nucleus breaksdown which is detached from the cytoplasm.protein formation called kinetochores is formed around the centromere.
In metaphase, centromere of the chromosomes line up at the spindle of the equator.
In anaphase the sister chromatics are separated from the centromere, they are pulled at the poles and each have identical set.
During telophase a nuclear membrane surrounds the each set of chromosomes and separate the nuclear DNA from cytoplasm.
