WebHow do eukaryotic Ribosome Binding Sites work? Initiation of protein synthesis in eukaryotes differs from this model. The 5' end of the mRNA has a modified chemical structure ("cap") recognized by the ribosome, which then binds the mRNA and moves along it ("scans") until it finds the first AUG codon.
