Question

Quizplus · Accepted Answer

The spindle apparatus begins to form during prophase as the centrosomes move towards the opposite poles of the cell and microtubules begin to extend from them, forming the spindle fibers that will later attach to the chromosomes during metaphase. Anaphase is characterized by the separation of sister chromatids towards opposite poles of the cell, while telophase involves the formation of new nuclei around each set of chromosomes. Interphase is the period between cell divisions when the cell grows, replicates its DNA, and prepares for mitosis or meiosis.
