WebA 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 cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the … WebMar 21, 2024 · The interphase is the longest phase of the cell cycle. it is estimated that the cell spends most of its life in interphase, which covers approximately 90 percent of the …

WebJul 7, 2024 · Before a dividing cell enters mitosis, it undergoes a period of growth called interphase. About 90 percent of a cell's time in the normal cell cycle may be spent in interphase. G1 phase: The period prior to the synthesis of DNA. In this phase, the cell increases in mass in preparation for cell division. The G1 phase is the first gap phase. WebThe cell cycle. In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. teaching license nc
