"Webb22 juni 2024 · Ultimately, translation has three steps: initiation, elongation, and termination. During initiation, the strand of mRNA forms a loop, and a small ribosomal subunit (the bottom of the ribosome) hooks onto it and finds a sequence of bases that signals it to begin transcription. This is called the start codon (AUG). " - Initiation during translation

WebbTranslation 1: Initiation. Inhaltliche Einleitung. Bei der Translation wird die mRNA in die Aminosäuresequenz übersetzt. Dies läuft in 3 Phasen ab, wobei die erste Phase, die Initiation, die Vorbereitung zur eigentlichen Synthese ist. Jeweils drei Basen der mRNA, die eine Kopie eines DNA-Abschnittes ist, kodieren für eine Aminosäure. WebbTranslation, the process of mRNA-encoded protein synthesis, requires a complex apparatus, composed of the ribosome, tRNAs and additional protein factors, including aminoacyl tRNA synthetases. The ribosome provides the platform for proper assembly of mRNA, tRNAs and protein factors and carries the peptidyl-transferase activity.
