What role do microtubeles play during mitosis?

During mitosis, microtubules play a crucial role in the formation of the mitotic spindle, which is essential for chromosome segregation. They help attach to the kinetochores of chromosomes, ensuring that sister chromatids are pulled apart and moved to opposite poles of the cell. Additionally, microtubules provide structural support and facilitate the overall organization of the dividing cell, ensuring accurate and efficient cell division.
