WebChromosome Dynamics During the Cell Cycle The G 1, S, and G 2 phases are often referred to as interphase, and the M phase is the mitotic phase. During interphase, chromosomes are replicated, and during mitosis they become highly condensed and then are separated and distributed to the two daughter nuclei. WebDuring S (synthesis) phase which occurs between G1 and G2 , all the somatic DNA replicates. So every chromosome gets copied and thus has a sister chromatid. Animals that undergo sexual reproduction have 2 sets …
