  2. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    In most bacteria the most numerous intracellular structure is the ribosome, the site of protein synthesis in all living organisms. All prokaryotes have 70S (where S= Svedberg units) ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. The 70S ribosome is made up of a 50S and 30S subunits.

  3. Bacterial cellular morphologies - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cellular...

    Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea). Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped ...

  4. Bacteria - Wikipedia

    en.wikipedia.org/wiki/Bacteria

    Bacteria can be classified on the basis of cell structure, cellular metabolism or on differences in cell components, such as DNA, fatty acids, pigments, antigens and quinones. [116] While these schemes allowed the identification and classification of bacterial strains, it was unclear whether these differences represented variation between ...

  5. Prokaryote - Wikipedia

    en.wikipedia.org/wiki/Prokaryote

    Prokaryotic cell structure Description Flagellum (not always present) Long, whip-like protrusion that aids cellular locomotion used by both gram-positive and gram-negative bacteria. Cell membrane: Surrounds the cell's cytoplasm and regulates the flow of substances in and out of the cell. Cell wall (except genera Mycoplasma and Thermoplasma)

  6. S-layer - Wikipedia

    en.wikipedia.org/wiki/S-layer

    An S-layer (surface layer) is a part of the cell envelope found in almost all archaea, as well as in many types of bacteria. [1][2] The S-layers of both archaea and bacteria consists of a monomolecular layer composed of only one (or, in a few cases, two) identical proteins or glycoproteins. [3] This structure is built via self-assembly and ...

  7. Bacterial capsule - Wikipedia

    en.wikipedia.org/wiki/Bacterial_capsule

    The bacterial capsule is a large structure common to many bacteria. [1] It is a polysaccharide layer that lies outside the cell envelope, and is thus deemed part of the outer envelope of a bacterial cell. It is a well-organized layer, not easily washed off, and it can be the cause of various diseases. [2][3]

  8. Lysogenic cycle - Wikipedia

    en.wikipedia.org/wiki/Lysogenic_cycle

    Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction (the lytic cycle being the other). Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. In this condition the bacterium continues to live and ...
