WebSummary. The cell cycle is made up of two main stages: interphase and mitosis. During interphase, cells are duplicating their material and synthesising proteins to prepare to divide. Interphase encompasses 3 phases: G1, S and G2. During S phase, DNA is replicated. Mitosis encompasses prophase, prometaphase, metaphase, anaphase telophase. WebConcept note-2: -The main cell cycle checkpoints are the G1/S checkpoint, the intra-S checkpoint, and the G2/M checkpoint [60]. The transition through stages of the cell …
WebThere are three major checkpoints in the cell cycle: one near the end of G 1, a second at the G 2 –M transition, and the third during metaphase. These regulatory checks serve to ensure that the processes required to successfully move on to the next phase of the cell cycle have been fully completed and that sufficient resources exist to move on to the …
