During metaphase each chromosome attaches to spindle fibers. The centriole anchors the spindle fibers and helps in splitting the chromosome.
Metaphase
There are six phases of mitosis (a way which allows cell to reproduce itself so that organisms can grow). In this process, DNA is coiled into chromosomes. In the second phase, the spindle fibers attach themselves to centromere - centromere is a part of chromosome linking two sister chromatids (2 chromsatids make one chromosome). In the fourth phase, these spindle fibers shorten themselves and the sister chromatids are physically separated by the action. This way the two diploid daughter cells produced in mitosis have 46 chromosomes each.
Centrioles begin to organize spindle fibers during the prophase of mitosis. In this phase, the centrosomes, which contain the centrioles, move to opposite poles of the cell, and the spindle fibers start to form from the microtubules organized by the centrioles. This organization is crucial for ensuring proper chromosome alignment and separation during cell division.
Centromere splitting is something that happens to the Chromosomes during the M Phase (Mitosis) of cell division. During Anaphase (a phase in the M Phase), the centrioles that have sent out spindle fibers and are at opposite poles just tug at the centromere of the Chromosome, causing the centromere to split. Anaphase is basically centromere splitting, where the spindle fibers from the centrioles split the chromosome in half at the centromere.
Microtubules form the spindle during the metaphase of cell division, specifically in mitosis and meiosis. In this phase, the spindle fibers, which are composed of microtubules, align the chromosomes at the cell's equatorial plane. This alignment is crucial for ensuring that each daughter cell receives an identical set of chromosomes during the subsequent anaphase. The proper formation and function of the spindle are essential for accurate chromosome segregation.

This way the two diploid daughter cells produced in mitosis have 46 chromosomes each.
Anaphase is the phase during mitosis when the sister chromatids are pulled apart by spindle fibers and move to opposite poles of the cell. This is a critical step in ensuring that each daughter cell receives a complete set of chromosomes with a copy of each chromosome.

The name for the network of microtubules along which the chromosomes move during cell division is called the spindle fibers. These spindle fibers attach to the chromosomes and pull them in half.
Chromosomes align at the center of the spindle during the metaphase stage of mitosis. This ensures that each chromosome is properly attached to the spindle fibers and aligned in a straight line to ensure accurate chromosome segregation during cell division.
Centrioles begin to organize spindle fibers during the prophase of mitosis. In this phase, the centrosomes, which contain the centrioles, move to opposite poles of the cell, and the spindle fibers start to form from the microtubules organized by the centrioles.

Anaphase is basically centromere splitting, where the spindle fibers from the centrioles split the chromosome in half at the centromere.
Anaphase is the phase in which chromosome strands separate and move towards opposite ends of the cell. This movement is facilitated by spindle fibers pulling the sister chromatids apart towards the centrosomes at opposite poles of the cell.
