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). Gamete: Now after meiosis, there are four daughter cells which if male, are four sperm cells and if female, are one egg cell and three other cells that form around the egg cell.This article is about the phase in the cell cycle.Telophase II: In this stage the cells start dividing and the nuclear membrane reforms around the chromatids.Anaphase II: This is the stage where the chromatids seperate and start moving towards opposite sides of the cells.Metaphase II: In this stage the sister chromatids line up at the center and the spindle fibres attach and start pulling on them.Prophase II: In this stage the centrosomes start moving to opposite sides of each cell.Telophase 1: In this stage the nuclear membrane forms again around the chromatid, the two daughter cells forming are haploid.Anaphase 1: In this stage the chromatids start moving to opposite ends of the cell as the spindle fibres pull.Metaphase 1: In this stage the chromatids line up in the center of the cell, and the spindle fibres attach to the chromatids.Prophase 1: In this stage the chromatids connect and cross over, this is when the chromatids trade sections.
