WebbTranslation initiation is the most highly regulated step of protein synthesis in prokaryotes. [5] The rate of translation depends on two factors: the rate at which a ribosome is recruited to the RBS the rate at which a recruited ribosome is able to initiate translation (i.e. the translation initiation efficiency)

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. lexus chennai showroomWebb31 aug. 2024 · Therefore this is the binding site for the 30S ribosomal subunit which then migrates in a 3’ direction along the mRNA until it encounters the AUG initiation codon.
