Ribosomes of eukaryotic cell
Webb2 feb. 2024 · Answer. 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.
