Microtubules in dividing cells emanate from centrosomes

Astral microtubules and nonkinetochore microtubules control and stabilize cell shape during division. Kinetochore microtubules attach to chromosome kinetochores to move chromosomesAstral microtubules and nonkinetochore microtubules control and stabilize cell shape during division.
