Webb21 nov. 2012 · In prokaryotes, the ribosomal binding site (RBS) is an A/G rich sequence that is 5–7 nucleotides upstream of the translational start codon [21]. The A/G content is important for gene expression. A change from A/G to T/C can significantly decrease or even block RBS activity [22]. jim hall rig rundown

Ribosome binding sites are a sequence of nucleotides upstream of the start (AUG) codon of an mRNA transcript. The ribosome recognizes and binds to a cap (a modified chemical structure) at the 5' end of the mRNA and moves along it until it finds the start codon or the first AUG codon. The Kozak sequence, which is a distinctive …
