6 Stages of Cell Cycle Latest Update 100% Solved Interphase The cell grows to its mature size, makes a copy of its DNA, and prepares to divide into two cells. Centrioles are also copied. Prophase Chromatin in the nucleus condenses to form chromosomes. Spindle Fibers form a bridge between the ends of the cell. Metaphase The chromosomes line up across the center of the cell. Each chromosome attaches to a spindle fiber at its centromere. Anaphase The centromeres split. The two chromatids separat...
