  2. Ribosomal RNA - Wikipedia

    en.wikipedia.org/wiki/Ribosomal_RNA

    Ribosomal RNA is the predominant form of RNA found in most cells; it makes up about 80% of cellular RNA despite never being translated into proteins itself. Ribosomes are composed of approximately 60% rRNA and 40% ribosomal proteins, though this ratio differs between prokaryotes and eukaryotes .

  3. Ribosome - Wikipedia

    en.wikipedia.org/wiki/Ribosome

    Ribosomal RNA composition for prokaryotes and eukaryotes. The ribosome is a complex cellular machine. It is largely made up of specialized RNA known as ribosomal RNA (rRNA) as well as dozens of distinct proteins (the exact number varies slightly between species). The ribosomal proteins and rRNAs are arranged into two distinct ribosomal pieces ...

    Transfer RNA (tRNA) is a small RNA chain of about 80 nucleotides that transfers a specific amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation. It has sites for amino acid attachment and an anticodon region for codon recognition that binds to a specific sequence on the messenger RNA chain ...

  6. Ribosome biogenesis - Wikipedia

    en.wikipedia.org/wiki/Ribosome_biogenesis

    If defective ribosomal subunits do happen to make it out of the nucleolus and into the cytoplasm, there is a second surveillance system in place there to target malfunctioning ribosomes in the cytoplasm for degradation. Certain mutations in residues of the large ribosome subunit will actually result in RNA decay and thus degradation of the unit.

    en.wikipedia.org/wiki/Eukaryotic_ribosome

    The ribosomal RNA core is represented as a grey tube, expansion segments are shown in red. Universally conserved proteins are shown in blue. These proteins have homologs in eukaryotes, archaea and bacteria. Proteins Shared only between eukaryotes and archaea are shown in orange, and proteins specific to eukaryotes are shown in red.

  8. Ribosomal DNA - Wikipedia

    en.wikipedia.org/wiki/Ribosomal_DNA

    The ribosomal DNA includes all genes coding for the non-coding structural ribosomal RNA molecules. Across all domains of life, these are the structural sequences of the small subunit (16S or 18S rRNA) and the large subunit (23S or 28S rRNA). The assembly of the latter also include the 5S rRNA as well as the additional 5.8S rRNA in eukaryotes.

  9. 5S ribosomal RNA - Wikipedia

    en.wikipedia.org/wiki/5S_ribosomal_RNA

    The 5S ribosomal RNA (5S rRNA) is an approximately 120 nucleotide-long ribosomal RNA molecule with a mass of 40 kDa.It is a structural and functional component of the large subunit of the ribosome in all domains of life (bacteria, archaea, and eukaryotes), with the exception of mitochondrial ribosomes of fungi and animals.
