5102715165G1 phaseThe cell grows physically larger, copies organelles, and makes the molecular building blocks it will need in later steps12
5102722849S PhaseThe cell synthesizes a complete copy of the DNA in its nucleus and duplicates the centrosome13
5102736377G2 PhaseThe cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.14
5102760710CytokinesisThe cytoplasm of the cell is split in two, making two new cells15
5102775876MitosisThe nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle Four stages: prophase, metaphase, anaphase, and telophase.16
5105521516GlycolysisOccurs in the cytoplasmic fluid of the the cell, that is, outside the organelles, begins respiration by breaking glucose into two molecules of a three-carbon compound called pyruvate17
