English: Translation: Illustrates how a ribosome a mRNA and lots of tRNA molecules work together to produce peptides or proteins. Français : Diagramme montrant comment la traduction de l'ARN messager et la synthèse protéique se font dans les ribosomes.
Translation initiation is the process by which the ribosome and its associated factors bind to an mRNA and are assembled at the start codon. This process is defined as either cap-dependent, in which the ribosome binds initially at the 5' cap and then travels to the stop codon, or as cap-independent, where the ribosome does not initially bind ...
One site of mRNA translation is at polyribosomes selectively localized beneath synapses. [14] The mRNA for Arc/Arg3.1 is induced by synaptic activity and localizes selectively near active synapses based on signals generated by NMDA receptors. [15] Other mRNAs also move into dendrites in response to external stimuli, such as β-actin mRNA. [16]
[1] [2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs protein synthesis. [2] [3] The mRNA sequence is determined by the sequence of genomic DNA. [4] In this context, the standard genetic code is referred to as ...

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 ...
Translation is the process by which a mature mRNA molecule is used as a template for synthesizing a new protein. [51]: 6.2 Translation is carried out by ribosomes, large complexes of RNA and protein responsible for carrying out the chemical reactions to add new amino acids to a growing polypeptide chain by the formation of peptide bonds.
The 30S subunit is an integral part of mRNA translation.It binds three prokaryotic initiation factors: IF-1, IF-2, and IF-3. [3]A portion of the 30S subunit (the 16S rRNA) guides the initiating start codon (5′)-AUG-(3′) of mRNA into position by recognizing the Shine-Dalgarno sequence, a complementary binding site about 8 base pairs upstream from the start codon.
