WebIn prokaryotes, the ribosome binding site (RBS), which promotes efficient and accurate translation of mRNA, is called the Shine-Dalgarno sequence after the scientists that first described it. This purine-rich sequence of 5′ UTR is complementary to the UCCU core sequence of the 3′-end of 16S rRNA (located within the 30S small ribosomal subunit). WebThe large ribosomal subunit joins the small subunit, and a second tRNA is recruited. As the mRNA moves relative to the ribosome, the polypeptide chain is formed. Entry of a release factor into the A site terminates translation and the components dissociate. Many antibiotics inhibit bacterial protein synthesis.
