    Ada E. Yonath (Hebrew: עדה יונת, pronounced [ˈada joˈnat]; born 22 June 1939) [1] is an Israeli crystallographer and Nobel laureate in Chemistry, best known for her pioneering work on the structure of ribosomes.

  3. Ribozyme - Wikipedia

    en.wikipedia.org/wiki/Ribozyme

    Called Ribosome-T, or Ribo-T, the artificial ribosome was created by Michael Jewett and Alexander Mankin. [41] The techniques used to create artificial ribozymes involve directed evolution. This approach takes advantage of RNA's dual nature as both a catalyst and an informational polymer, making it easy for an investigator to produce vast ...

    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.

  5. Eukaryotic translation - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_translation

    Upon termination, the ribosome is disassembled and the completed polypeptide is released. eRF3 is a ribosome-dependent GTPase that helps eRF1 release the completed polypeptide. The human genome encodes a few genes whose mRNA stop codon are surprisingly leaky: In these genes, termination of translation is inefficient due to special RNA bases in ...

    Examples include ribosomes, nucleosomes, and many enzymes. nucleosidase Any of a class of enzymes which catalyze the decomposition of nucleosides into their component nitrogenous bases and pentose sugars. [12] nucleoside An organic molecule composed of a nitrogenous base bonded to a five-carbon sugar (either ribose or deoxyribose).

  7. Ribosomal protein - Wikipedia

    en.wikipedia.org/wiki/Ribosomal_protein

    The ribosome of E. coli has about 22 proteins in the small subunit (labelled S1 to S22) and 33 proteins in the large subunit (somewhat counter-intuitively called L1 to L36). All of them are different with three exceptions: one protein is found in both subunits (S20 and L26), [ dubious – discuss ] L7 and L12 are acetylated and methylated forms ...

    The nucleolus (/ nj uː ˈ k l iː ə l ə s, ˌ nj uː k l i ˈ oʊ l ə s /; pl.: nucleoli /-l aɪ /) is the largest structure in the nucleus of eukaryotic cells. [1] It is best known as the site of ribosome biogenesis.
