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. WebPhases of cell cycle: G0, G1, S, G2, M. The cell cycle has two major phases: interphase (G0, G1, S, G2) and the mitotic phase (M). The cell cycle is an ordered series of events involving cell growth and cell division … The G1 phase, gap 1 phase, or growth 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of interphase, the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis. G1 phase ends when the cell moves into the S phase of interphase. Around 30 to 40 percent of cell cycle time is spent in the G1 phase. graphic service siena
