  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 ...

  4. Ribosome biogenesis - Wikipedia

    en.wikipedia.org/wiki/Ribosome_biogenesis

    Ribosomes are the macromolecular machines that are responsible for mRNA translation into proteins. The eukaryotic ribosome, also called the 80S ribosome, is made up of two subunits – the large 60S subunit (which contains the 25S [in plants] or 28S [in mammals], 5.8S, and 5S rRNA and 46 ribosomal proteins) and a small 40S subunit (which contains the 18S rRNA and 33 ribosomal proteins).

  5. RNA - Wikipedia

    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. Translation (biology) - Wikipedia

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

    Overview of eukaryotic messenger RNA (mRNA) translation Translation of mRNA and ribosomal protein synthesis Initiation and elongation stages of translation involving RNA nucleobases, the ribosome, transfer RNA, and amino acids The three phases of translation: (1) in initiation, the small ribosomal subunit binds to the RNA strand and the initiator tRNA–amino acid complex binds to the start ...

  7. RNA polymerase - Wikipedia

    en.wikipedia.org/wiki/RNA_polymerase

    RNAP produces RNA that, functionally, is either for protein coding, i.e. messenger RNA (mRNA); or non-coding (so-called "RNA genes"). Examples of four functional types of RNA genes are: Transfer RNA (tRNA) Transfers specific amino acids to growing polypeptide chains at the ribosomal site of protein synthesis during translation; Ribosomal RNA (rRNA)

  8. Eukaryotic ribosome - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_ribosome

    The 40S subunit contains a 18S ribosomal RNA (abbreviated 18S rRNA), which is homologous to the prokaryotic 16S rRNA. The 60S subunit contains a 28S rRNA that is homologous to the prokaryotic 23S ribosomal RNA. In addition, it contains a 5.8S rRNA that corresponds to the 5' end of the 23S rRNA, and a short 5S rRNA.
