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. ca notice of state tax lienWebPairing of homologus chromosomes in a diploid cell, as occurs during prophase I of meiosis.
