What exact point of "beginning of mitosis"? is that prophase or G1??? #2. all of the following statements are true except a. spindle fibers are composed largely of microtubules. b. centrioles consist of nine triplets of microtubules arranged in a circle c. all eukaryotic cells have centrioles d. all eukaryotic cells have a spindle apparatus e. many of the microtubules in a spindle apparatus attach to kinetochores of chromosomes ==> answer : C. why not D???
