Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions. Interphase is the phase of the cell cycle in which a typical cell spends most of its life. ![]() The cell is quiescent only in the sense of cell division (i.e. dormant) would be misleading since a cell in interphase is very busy synthesizing proteins, copying DNA into RNA, engulfing extracellular material, processing signals, to name just a few activities. A cell in interphase is not simply quiescent. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. ![]() Image taken using an optical microscope and DAPI staining of DNA. Note: Cytoplasm of this cell or the neighboring cell is not visible (top-left), which is currently in the telophase of mitosis. An image of the nucleus of a cell ( HT1080) currently in interphase (likely G1). The chromatin has not yet condensed, and the cell is undergoing its normal functions. ![]() For the video game, see Interphase (video game). This article is about the phase in the cell cycle.
