WebProphase I (Stage 2) The DNA starts to coil itself up into visible chromosomes. The copies of each chromosome (sister chromatids) are connected together by a centromere. During the end of this stage the nuclear membrane starts to dissolve, centrosomes move towards the poles, and spindle fibers start to form. Crossing over occurs during this stage.
