They can either float freely in the cell or sit on the surface of the rough endoplasmic reticulum in eukaryotic cells, (giving it the designation of "rough," in comparison to its smooth sibling that lacks ribosomes).

WebThe classical two-state model [4] proposes that the ribosome contains two binding sites for tRNA, P-site and A-site. The A-site binds to incoming aminoacyl-tRNA which has the anti-codon for the corresponding codon in the mRNA presented in the A-site.
