How Can You Describe Interphase?

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.

  1. Learn about the gap one (G1) phase

    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.

  2. Disvover the synthesis (S) phase

    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.

  3. Finish with the gap two (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.
