WebDuring prophase I, differences from mitosis begin to appear. As in mitosis, the chromosomes begin to condense, but in meiosis I, they also pair up. Each chromosome carefully aligns with its homologue partner so that the two match up at corresponding positions along their full length. WebDec 17, 2016 · During interphase preceding mitosis, the chromosomes exist in a loose state. At the onset of prophase, proteins associated with the DNA are activated, and the DNA winds around them and bundles in dense shapes.
