Cell Cycle (Mitosis) Latest 2024 Graded A+ cell cycle An ordered sequence of events in the life of a cell mitosis Cell division in which the nucleus divides into nuclei containing the same number of chromosomes what are the four stages of mitosis? Prophase Metaphase Anaphase Telophase prophase first phase of mitosis, during which the chromatin changes into chromosomes, spindle fibers form & the nuclear membrane disappears metaphase the second stage in mitosis in which the duplicated chromosomes line up along the equatorial plate in the middle of the cell. anaphase the third phase of mitosis , the chromatids of each chromosome separate/ split at the centromere and move in opposite directions telophase The fourth and final stage of mitosis, in which two nuclear membranes form & chromosomes change into chromatin cytokinesis division of the cytoplasm & its organelles after mitosis is complete chromosomes a piece of chromatin that has folded many times to form a thick structure that stains dark and is visible with a light microscope. chromatin Combination of DNA and its histone proteins in the nucleus. sister chromatids Duplicate copies of DNA attached at a centromere; two attached chromatids make the typical X shape of a chromosome interphase A period of growth and DNA synthesis when the cell is not actually in the process of dividing. spindle fibers protein fibers that attach to chromatids and assist in their separation during mitosis. G1 Phase first growth stage of interphase in which cell grows and performs its normal functions S Phase the portion of interphase during which DNA is replicated. G2 Phase The second growth phase, of the cell cycle, Cells prepare to divide and wait for a signal gene one small portion of chromatin with the instructions to build one protein
