Web17 jan. 2024 · The phases of the cell cycle include Interphase and the Mitotic phase. Interphase consists of the Gap 1 phase (G 1), Synthesis phase (S), and Gap 2 phase (G 2). Dividing cells spend most of their time in interphase, in which they increase in mass and replicate DNA in preparation for cell division. WebDuring the S-phase of interphase, the DNA is replicated, forming two identical sets of DNA. At the beginning of mitosis, the DNA condenses and coils into structures called chromosomes.
