_______ During what phase of mitosis do centrioles form spindle fibers that will eventually help the chromosomes move toward their respective poles?
_______ What is the phase where chromatin condenses into visible chromosomes?
_______ What is the name of the structure that connects the two sister chromatids?
_______ What is each piece called of a doubled-chromosome referred to (these pieces are attached at the centromere)?
