  2. Metaphase - Wikipedia

    en.wikipedia.org/wiki/Metaphase

    Metaphase (from Ancient Greek μετα- beyond, above, transcending and from Ancient Greek φάσις (phásis) 'appearance') is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase). [1]

  3. G2 phase - Wikipedia

    en.wikipedia.org/wiki/G2_phase

    This interval includes the G 2 phase and metaphase (annotated as "Meta."). Further information: Karyotype G 2 phase , Gap 2 phase , or Growth 2 phase , is the third subphase of interphase in the cell cycle directly preceding mitosis .

  4. Mitosis - Wikipedia

    en.wikipedia.org/wiki/Mitosis

    Numerous descriptions of cell division were made during 18th and 19th centuries, with various degrees of accuracy. [13] In 1835, ... Metaphase: The centrosomes have ...

  5. PMAT - Wikipedia

    en.wikipedia.org/wiki/PMAT

    Four phases of mitosis: prophase, metaphase, anaphase, and telophase: Prophase: Chromatin into chromosomes, the nuclear envelope breaks down, chromosomes attach to spindle fibers by their centromeres. Metaphase: Chromosomes line up along the metaphase plate (center of the cell). Anaphase: Sister chromatids are pulled to opposite poles of the cell.

  6. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    The last check point is located at the site of metaphase, where it checks that the chromosomes are correctly connected to the mitotic spindles. [17] In S phase, the chromosomes are replicated in order for the genetic content to be maintained. [18]

  7. G1 phase - Wikipedia

    en.wikipedia.org/wiki/G1_phase

    Schematic karyogram of the human chromosomes, showing their usual state in the G 0 and G 1 phase of the cell cycle. At top center it also shows the chromosome 3 pair in metaphase (annotated as "Meta."), which takes place after having undergone DNA synthesis which occurs in the S phase (annotated as S) of the cell cycle.

  8. Spindle apparatus - Wikipedia

    en.wikipedia.org/wiki/Spindle_apparatus

    Micrograph showing condensed chromosomes in blue, kinetochores in pink, and microtubules in green during metaphase of mitosis. In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells.

  9. Cell cycle checkpoint - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle_checkpoint

    There are many checkpoints in the cell cycle, [1] but the three major ones are: the G1 checkpoint, also known as the Start or restriction checkpoint or Major Checkpoint; the G2/M checkpoint; and the metaphase-to-anaphase transition, also known as the spindle checkpoint. [2]
