Unformatted text preview: are brought together. On the ribosome, the mRNA fits between the two subunits (the interactions are stabilized by interchain hydrogen bonding). The tRNAs occupy a site on the large ribosomal subunit. The ribosome attaches to the mRNA at or near the 5'end. In prokaryotes there is a ribosome binding site near the 5'end of the mRNA. In eukaryotes, the ribosome first attaches at the 5'CAP (7-methyl guanosine). The ribosome then moves along the mRNA in the 5' to 3' direction, one codon at a time....
