WitrynaA cell spends most of its life in interphase, which has three phases: G1, S, and G2. In the G1 phase, the cell grows and takes in nutrients. In the S phase, the cell's DNA is replicated. Each replicated chromosome consists of two sister chromatids connected at the centromere. The G2 phase is another growth phase, after which the cell is ready ... WitrynaAs in mitosis, the cell grows during G _1 1 phase, copies all of its chromosomes during S phase, and prepares for division during G _2 2 phase. During prophase I, differences from mitosis begin to appear. As in mitosis, the chromosomes begin to condense, …
