  2. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    Cell division is the process by which a parent cell divides into two daughter cells, either genetically identical (mitosis) or with reduced chromosomes (meiosis). Learn about the different forms of cell division in prokaryotes and eukaryotes, and the stages of the cell cycle and DNA replication.

  3. Mitosis - Wikipedia

    en.wikipedia.org/wiki/Mitosis

    Mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei, producing genetically identical cells. Learn about the stages, variations, and history of mitosis, and how it differs from meiosis and binary fission.

  4. Mitochondrion - Wikipedia

    en.wikipedia.org/wiki/Mitochondrion

    A mitochondrion is an organelle that uses aerobic respiration to generate ATP, the chemical energy of the cell. The process of aerobic respiration is called oxidative phosphorylation, which occurs in the inner membrane of the mitochondrion.

  5. Cell cycle - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle

    The cell cycle is the series of events that cause a cell to divide into two daughter cells. It consists of interphase and M phase, which include DNA replication, mitosis, and cytokinesis. Learn about the stages, checkpoints, and control mechanisms of the cell cycle.

  6. Biochemical switches in the cell cycle - Wikipedia

    en.wikipedia.org/wiki/Biochemical_switches_in...

    The interaction between the two types of loops is evident in mitosis. While positive feedback initiates mitosis, a negative feedback loop promotes the inactivation of the cyclin-dependent kinases by the anaphase-promoting complex. This example clearly shows the combined effects that positive and negative feedback loops have on cell-cycle ...

  7. Microtubule organizing center - Wikipedia

    en.wikipedia.org/wiki/Microtubule_organizing_center

    The microtubule organizing center (MTOC) is a structure that nucleates and organizes microtubules in eukaryotic cells. MTOCs have different forms and functions in animals, plants, and fungi, such as flagella, cilia, spindle formation, and signal transduction.

  8. G1 phase - Wikipedia

    en.wikipedia.org/wiki/G1_phase

    G1 phase is the first phase of interphase in eukaryotic cell division, where the cell grows and prepares for DNA synthesis. Learn about the biochemical triggers, checkpoints and restrictions that control the G1 phase, and how it relates to cancer and cell cycle regulation.

  9. Mitochondrial biogenesis - Wikipedia

    en.wikipedia.org/wiki/Mitochondrial_biogenesis

    Learn about the process by which cells increase mitochondrial numbers and how it is regulated by various signals and proteins. Find out the evolutionary history, metabolic functions, and fusion/fission events of mitochondria.
