The English language draws a terminological distinction (which does not exist in every language) between translating (a written text) and interpreting (oral or signed communication between users of different languages); under this distinction, translation can begin only after the appearance of writing within a language community.
The process of amino acid building to create protein in translation is a subject of various physic models for a long time starting from the first detailed kinetic models such as [24] or others taking into account stochastic aspects of translation and using computer simulations. Many chemical kinetics-based models of protein synthesis have been ...
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 ...
Translation of the uORF2 requires that the ribosomes pass by the ATF4 ORF, whose start codon is located within uORF2. This leads to its repression. This leads to its repression. However, during stress conditions, the 40S ribosome will bypass uORF2 because of a decrease in concentration of eIF2-TC, which means the ribosome does not acquire one ...
The start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome. The start codon always codes for methionine in eukaryotes and archaea and a N-formylmethionine in bacteria, mitochondria and plastids. The start codon is often preceded by a 5' untranslated region .
The ribosome assembles on the start codon (AUG), located within the Kozak sequence. Prior to translation initiation, scanning is done by the pre-initiation complex (PIC). The PIC consists of the 40S (small ribosomal subunit) bound to the ternary complex, eIF2-GTP-intiatorMet tRNA (TC) to form the 43S ribo

The mRNA then pairs up with this anti-SD region, causing it to form a double-stranded RNA structure, roughly positioning the start codon at the P site. An initiating tRNA fMet arrives and is positioned with the help of IF2, starting the translation. [1] There are a lot of uncertainties even in the canonical model.
