  2. Transfer RNA - Wikipedia

    en.wikipedia.org/wiki/Transfer_RNA

    The amino acid loaded onto the tRNA by aminoacyl tRNA synthetases, to form aminoacyl-tRNA, is covalently bonded to the 3′-hydroxyl group on the CCA tail. [9] This sequence is important for the recognition of tRNA by enzymes and critical in translation. [10] [11] In prokaryotes, the CCA sequence is transcribed in some tRNA sequences. In most ...

  3. Cloverleaf model of tRNA - Wikipedia

    en.wikipedia.org/wiki/Cloverleaf_model_of_tRNA

    Secondary cloverleaf structure of tRNA Phe from yeast.. The cloverleaf model of tRNA is a model that depicts the molecular structure of tRNA. [1] The model revealed that the chain of tRNA consists of two ends—sometimes called "business ends"—and three arms.

  4. Threose nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Threose_nucleic_acid

    [8] [9] [10] Such experiments demonstrate that the properties of heredity and evolution are not limited to the natural genetic polymers of DNA and RNA. [11] The high biological stability of TNA relative to other nucleic acid systems that are capable of undergoing Darwinian evolution, suggests that TNA is a strong candidate for the development ...

  5. Aminoacyl-tRNA - Wikipedia

    en.wikipedia.org/wiki/Aminoacyl-tRNA

    An aminoacyl-tRNA, with the tRNA above the arrow and a generic amino acid below the arrow. Most of the tRNA structure is shown as a simplified, colorful ball-and-stick model; the terminal adenosine and the amino acid are shown as structural formulas.

  6. Aminoacyl tRNA synthetase - Wikipedia

    en.wikipedia.org/wiki/Aminoacyl_tRNA_synthetase

    The synthetase first binds ATP and the corresponding amino acid (or its precursor) to form an aminoacyl-adenylate, releasing inorganic pyrophosphate (PPi).The adenylate-aaRS complex then binds the appropriate tRNA molecule's D arm, and the amino acid is transferred from the aa-AMP to either the 2'- or the 3'-OH of the last tRNA nucleotide (A76) at the 3'-end.

  7. Nirenberg and Leder experiment - Wikipedia

    en.wikipedia.org/wiki/Nirenberg_and_Leder_experiment

    Working independently, Khorana had mastered the synthesis of nucleic acids, and Holley had discovered the exact chemical structure of transfer-RNA. The New York Times said of Nirenberg's work that "the science of biology has reached a new frontier," leading to "a revolution far greater in its potential significance than the atomic or hydrogen ...

  8. Bacterial translation - Wikipedia

    en.wikipedia.org/wiki/Bacterial_translation

    Initiation of translation in bacteria involves the assembly of the components of the translation system, which are: the two ribosomal subunits (50S and 30S subunits); the mature mRNA to be translated; the tRNA charged with N-formylmethionine (the first amino acid in the nascent peptide); guanosine triphosphate (GTP) as a source of energy, and the three prokaryotic initiation factors IF1, IF2 ...

  9. tRNA nucleotidyltransferase - Wikipedia

    en.wikipedia.org/wiki/TRNA_nucleotidyltransferase

    In vivo experiments show that the N-terminal sequences are used as transit peptides for import into the mitochondria and plastids. Comparison studies using available tRNA nucleotidyltransferase sequences have identified a single gene coding for this enzyme in plants.
