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.
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.
The phase you are referring to is called prometaphase. During prometaphase, the microtubules attach to the kinetochores at the centromere of each chromosome, allowing them to move and align properly along the metaphase plate in preparation for separation during anaphase.

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.
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.
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.
During Mitosis, the spindle pulls apart the sister chromatids of the chromosome in the Anaphase stage.
The phase you are referring to is called prometaphase. During prometaphase, the microtubules attach to the kinetochores at the centromere of each chromosome, allowing them to move and align properly along the metaphase plate in preparation for separation during anaphase.
