Microtubules attach to the to a structure on the sister chromatids called the kinetochore. Throwing the chromosomes into an agitated motion moving them towards the center of the cell. Then during anaphase they will help with the migration of chromosomes to opposite ends of the cell.
Microtubules and microfilaments are cellular cytoskeletal networks. Microtubules are tubular proteins made by tubulin polymers. they have role in cell structure, cell movement, mitosis, gene regulation and so on.

Microfilaments and microtubules
Microtubules are cyclindrical shaped polymers that help maintain and stabilize cell structure. They also have a major role in the transportation of molecules within the cell. They are part of the cytoskeleton, and the cytoskeleton is considered to be an organelle. The microtubules are only a fraction of an organelle under the cytoskeleton.
Microtubules are conveyor belts inside the cells. They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins. They also serve a cytoskeletal role. (from cytochemistry.net)
Microtubules are structured around a cell region called the centrosome
centriole
The centrioles are organelles in the cell that sends out microtubules that connect to the DBA during the metaphase. These centrioles determine the position of the nucleus and plays a crucial role in the spatial arrangement of the cell.
Microtubules radiate from the cell center.
kinetochore microtubules are located in the centrosomes and produce the microtubules
The Cytoskeleton is a system of microtubules, in a cell.
