WebProphase I First process of meiosis I in which: -The chromosomes begin to condense -The spindle of microtubules begins to form -The DNA has been replicated -Each chromosome consists of two sister chromatids attached at the centromere -Homologous chromosomes pair up and become closely associated during synapsis -Nuclear envelope is dispersed 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.
