  2. Fission (biology) - Wikipedia

    en.wikipedia.org/wiki/Fission_(biology)

    Binary fission is generally rapid, though its speed varies between species. For E. coli, cells typically divide about every 20 minutes at 37 °C. [11] Because the new cells will, in turn, undergo binary fission on their own, the time binary fission requires is also the time the bacterial culture requires to double in the number of cells it ...

  3. Bacterial growth - Wikipedia

    en.wikipedia.org/wiki/Bacterial_growth

    Bacterial growth is proliferation of bacterium into two daughter cells, in a process called binary fission. Providing no mutation event occurs, the resulting daughter cells are genetically identical to the original cell. Hence, bacterial growth occurs. Both daughter cells from the division do not necessarily survive.

  4. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    Cell division in prokaryotes (binary fission) and eukaryotes (mitosis and meiosis). The thick lines are chromosomes, and the thin blue lines are fibers pulling on the chromosomes and pushing the ends of the cell apart. The cell cycle in eukaryotes: I = Interphase, M = Mitosis, G 0 = Gap 0, G 1 = Gap 1, G 2 = Gap 2, S = Synthesis, G 3 = Gap 3.

  5. Cleavage furrow - Wikipedia

    en.wikipedia.org/wiki/Cleavage_furrow

    Cilliate undergoing the last processes of binary fission, with the cleavage furrow being clearly visible. In cell biology, the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell ...

  6. Nuclear ensemble approach - Wikipedia

    en.wikipedia.org/wiki/Nuclear_ensemble_approach

    The Nuclear Ensemble Approach (NEA) is a general method for simulations of diverse types of molecular spectra. [1] It works by sampling an ensemble of molecular conformations (nuclear geometries) in the source state, computing the transition probabilities to the target states for each of these geometries, and performing a sum over all these transitions convoluted with shape function.

  7. Cytokinesis - Wikipedia

    en.wikipedia.org/wiki/Cytokinesis

    Cytokinesis largely resembles the prokaryotic process of binary fission, but because of differences between prokaryotic and eukaryotic cell structures and functions, the mechanisms differ. For instance, a bacterial cell has a Circular chromosome (a single chromosome in the form of a closed loop), in contrast to the linear , usually multiple ...

  8. Fragmentation (reproduction) - Wikipedia

    en.wikipedia.org/wiki/Fragmentation_(reproduction)

    Many species of annelids and flatworms produce by this method. When the splitting occurs due to specific developmental changes, the terms orchiectomy, laparotomy, and budding are used. In 'architomy' the animal splits at a particular point and the two fragments regenerate the missing organs and tissues. The splitting is not preceded by the ...

  9. Thermochronology - Wikipedia

    en.wikipedia.org/wiki/Thermochronology

    Fission tracks observed in a mineral under optical microscope. Fission track dating is the method used in thermochronology to find the approximate age of several uranium-rich minerals, such as apatite. When nuclear fission of uranium-238 (238 U) happens in inorganic materials, damage tracks are
