The first interphase is the G1 phase, also known as. gap phase During this phase, the cell grows and prepares for DNA synthesis. Mitochondrial respiration provides the energy needed for growth. After the G1 phase, the cell goes through the. first checkpoint, checkpoint G1, officially called the restriction point. At this point, if there is DNA damage or other external factors, this is not the case. I'm not moving on to the next phase. Instead of proceeding to the next phase, the cell is killed before engaging in the cell cycle. The second interphase is the G2 phase, also known as the synthesis phase. It is in this phase that DNA duplication occurs and all chromosomes are replicated. DNA polymerases are used to synthesize DNA molecules essential for duplication. After synthesis, the cell goes through checkpoint S. This checkpoint ensures that all the chromosomes and DNA that have been replicated are not damaged, so that the cell can go further to the third interphase . The final interphase is phase G2, also known as gap phase two. During this phase, the cell continues to grow and prepares for mitosis. Biosynthesis occurs and involves the production of microtubules necessary for the mitosis phase. After passing through the final interphase, the cell passes through checkpoint G2. This point certifies that the replicated DNA is not damaged and that all chromosomes have been replicated. The cell is then able to go through the stage of mitosis. The mitosis stage is composed of three substages, the prophase stage, the metaphase stage, the anaphase stage and the telophase stage. During prophase, mediated by the condensin complex, chromatin condenses into the chromosome structure. This process is called chromatin condensation. The condensed, tightly coiled chromosomes then move to metaphase, where they line up in the middle of the cell and then separate into two daughter cells. The daughter cells then pass through the M checkpoint, at this point it is determined if the sister chromatids are properly attached to the spindle microtublues, if properly attached the cell can enter anaphase. The two daughter cells proceed to the next anaphase. In anaphase, all the chromatids separate and align with the spindle fibers. Then in telophase, the cell membrane is formed, nucleoli appear and all other organelles. The two daughter cells are fully formed. There is an additional stage to the cell cycle called the G0 stage. This is called the resting phase and cells are said to rest in this phase which can be reversible (quiescence) if they receive a division signal or irreversible (senescence). The cells there are alive and perform their functions, but are not preparing for division. Keep in mind: this is just a sample. Get a personalized article from our expert writers now. Get a"
