During mitosis, chromosomes are moved and separated through the use of spindles composed of microtubule structures.
Explanation:
Throughout mitosis, the chromosomes are initial replicated (copied) and so distributed into a pair of new "daughter" cells. They're replicated throughout the S section of interphase, and within the following phases (prophase, metaphase, anaphase, telophase) are organized, separated, and repackaged at opposite ends of the cell, at that purpose the cell divides. The strand of chromosomes split just like the cell throughout the cellular division. They split in half.
