    Hello and thank you for posting your question to Brainmass.

    From: http://biology.about.com/od/mitosis/ss/mitosisstep_2.htm

    In prophase, the chromatin condenses into discrete chromosomes. The nuclear envelope breaks down and spindles form at opposite "poles" of the cell. Many consider prophase (versus interphase) to be the first true step of the mitotic process.

    Solution Summary

    DNA replication is demonstrated.
