Web5 mrt. 2024 · Steps of Transcription. Transcription takes place in three steps: initiation, elongation, and termination. The steps are illustrated in Figure below.. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter.This signals the DNA to unwind so the enzyme can ‘‘read’’ … http://uro.dailyview.tw/can-a-single-mrna-be-translated-multiple-times/

WebAn mRNA that lacks the Kozak consensus sequence may be translated efficiently in eukaryotic cell-free systems if it possesses a moderately long 5'-untranslated region (UTR) that lacks stable secondary structure. In bacteria, the ribosome is guided to the AUG initiation site by a purine-rich region called the Shine-Dalgarno (SD) sequence. Web15 apr. 2024 · Messenger RNA (mRNA) translation and mRNA degradation are important determinants of protein output, and they are interconnected. Previously, it was thought that translation of an mRNA, as a rule, prevents its degradation. mRNA surveillance mechanisms, which degrade mRNAs as a consequence of their tr … Web16 mrt. 2024 · A single transcript can be read by multiple ribosomes at the same time forming a complex known as polysome (Munro et al. 1964). Once engaged, polysome will translate the mRNAs and would not readily exchange it for newly added mRNA until the translation of the initial mRNA is completed (Thompson and Gilbert 2024).
