  • Cell cycle | Description, Stages, Checkpoints, Facts | Britannica
    The cell cycle is the ordered sequence of events that occur in a cell in preparation for division The cell cycle is a four-stage process in which the cell increases in size, copies its DNA, prepares to divide, and ultimately divides

    Learn how your cells turn genetic instructions into working proteins, from DNA transcription to folding and final modifications
  • What Happens During the G1, S, and G2 Phases?
    Between one cell division and the next, a cell spends most of its life in a stretch called interphase, which breaks down into three distinct stages: G1, S, and G2 During G1, the cell grows in size and ramps up protein production During S phase, it copies its entire genome
