NO When in replication occurring? The S phase (synthesis phase) which is part of interphase What are the two gap phases? G1: first gap phase; occurs before S phase G2: second gap; occurs between S phase and mitosis Now put all of those steps in order, starting with the fist gap phase. G1 S phase G2 Mitosis Which lasts longer, interphase or m phase? Interphase What has happened in the picture below? the chromosomes just went through S phase and have been replicated! What has happened in the picture below and what phase are we in? the chromosomes have condensed; this is the of Mitosis (m phase) Complete the chart by saying what happens in each phase of Mitosis. Prophase Prometaphase Metaphase Anaphase Telophase -Chromosomes -start to see a -formation of -centromeres -new nuclear condense and breakdown of the mitotic split envelope begins become visible the nuclear spindle is -sister to form around in the light envelope complete chromatids are each set of microscope. -chromosomes pulled by the chromosomes -spindle line up in the spindle fibers -the mitotic apparatus middle on toward opposite spindle begins to form metaphase plate poles. Now that disintegrates they’ve split -the they are chromosomes
