Which of the following statements about the function of the centrosome is FALSE? Microtubules emanating from the centrosome have alternating polarity such that some have their attached to the centrosome while others have their minus end attached. Centrosomes contain y-tubulin ring complexes important for microtubule nucleation. Centrosomes typically contain a pair of centrioles made of short microtubules. Centrosomes are the major microtubule-organizing center in animal cells. Two centrosomes form the mitotic spindle during cell division.
