  2. Translation (biology) - Wikipedia

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

    In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates. The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time.

  3. Adaptor hypothesis - Wikipedia

    en.wikipedia.org/wiki/Adaptor_hypothesis

    [28] This is because it was the first comprehensive insight into genetic information (later called the central dogma of molecular biology), protein synthesis (known as the sequence hypothesis), the role of RNA (the adaptor hypothesis) as well as the existence of genetic code.

  4. Protein metabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_metabolism

    Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding. Proteins are made from amino acids. In humans, some amino acids can be synthesized using already existing intermediates. These amino ...

  5. Protein biosynthesis - Wikipedia

    en.wikipedia.org/wiki/Protein_biosynthesis

    Protein synthesis is a very similar process for both prokaryotes and eukaryotes but there are some distinct differences. [1] Protein synthesis can be divided broadly into two phases: transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a molecule called messenger RNA (mRNA).

  6. Bacterial translation - Wikipedia

    en.wikipedia.org/wiki/Bacterial_translation

    A third protein that can bind to ribosomes when E. coli cells enter the stationary phase is YfiA (previously known as RaiA). [22] HPF and YfiA are structurally similar, and both proteins can bind to the catalytic A- and P-sites of the ribosome. [23] [24] RMF blocks ribosome binding to mRNA by preventing interaction of the messenger with 16S ...

  7. Biomolecule - Wikipedia

    en.wikipedia.org/wiki/Biomolecule

    Modified amino acids are sometimes observed in proteins; this is usually the result of enzymatic modification after translation (protein synthesis). For example, phosphorylation of serine by kinases and dephosphorylation by phosphatases is an important control mechanism in the cell cycle .

  8. Guanosine triphosphate - Wikipedia

    en.wikipedia.org/wiki/Guanosine_triphosphate

    Guanosine-5'-triphosphate (GTP) is a purine nucleoside triphosphate.It is one of the building blocks needed for the synthesis of RNA during the transcription process. Its structure is similar to that of the guanosine nucleoside, the only difference being that nucleotides like GTP have phosphates on their ribose sugar.

  9. 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.
