A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. 2. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain or polypeptide. Role of ribosomes in translation: 1.

"WebbTranslation initiation, the first stage in protein synthesis, is the process of assembly of large (60S) and small (40S) ribosomal subunits to form an 80S ribosome containing initiator transfer RNA (tRNA) (Met-tRNAiMet) that is base paired to the initiation codon of a messenger RNA in the ribosomal peptidyl (P) site.

Mechanisms of Protein Synthesis by the Ribosome

WebbThe Process of Translation. Translation is generally divided into three stages: initiation, elongation, and termination ( Figure 7.8 ). In both prokaryotes and eukaryotes the first step of the initiation stage is the … WebbTranslation termination in eukaryotes occurs in response to a stop codon in the ribosomal A-site and requires two release factors (RFs), eRF1 and eRF3, which bind to the A-site as an eRF1/eRF3/GTP complex with eRF1 responsible for codon recognition. After GTP hydrolysis by eRF3, eRF1 triggers hydrolysis of the polypeptidyl-tRNA, releasing the ...
