Interphase is the phase of the cell cycle in which the growth of cells and metabolic activity occur, but nuclear division does not. There are three stages in interphase: G1, S and G2.Know More
The first stage of interphase is the G1 phase. During this stage, a new cell activates certain genes in its DNA in order to produce proteins. This process spurs on the metabolism of the cell that results in the production and breakdown of carbohydrates and lipids. The cell grows during this stage and converts food into energy from ATP.
The synthesis stage of interphase occurs after the G1 stage and begins with the replication of cellular DNA. Complex teams of enzymes copy the DNA molecules of each chromosome. When the cells contain nearly double the original amount of chromosomes, they move on to the G2 phase.
The final stage of interphase, the G2 phase, is when the cells prepare for division. An increase in synthesis of RNA and protein occurs, and the cells spend additional time checking and repairing the newly formed DNA sequences. This phase ends interphase. From here, cells continue on to the mitotic cycle of the cell cycle.
The longest part of the cell cycle is interphase. During interphase, the cell undergoes a growth phase in which it acquires energy to copy DNA. Once the DNA is copied, the cell undergoes another growth stage and acquires energy to complete cell division.Full Answer >
DNA is replicated during interphase, the phase of the cell cycle that precedes the four stages of mitosis: anaphase, prophase, prometaphase and telophase. According to CyberBridge, a life sciences website maintained by Harvard University, DNA replication occurs during the S phase of interphase.Full Answer >
The longest phase of the cell cycle is the Gap 1 phase, or G1 phase. During this phase, the cell gears up for cell division by amassing more organelles and getting larger.Full Answer >
The M phase in the cell cycle is known as the mitotic phase and is comprised of mitosis and cytokinesis. The outcome of the M phase is two distinct but identical daughter cells with the same genetic material.Full Answer >
