The 5S and 23S rRNAs are found within the large ribosomal subunit, while the 16S rRNA is located in the small ribosomal subunit. Eukaryotes, on the other hand, have at least 4 flavors of rRNA: 5S, 5.8S, 18S and 28S rRNAs. WebIt consists of two subunits.The smaller subunit binds to the mRNA strand and the larger subunit holds the tRNA molecules in placewhile the covalent peptide bond is formed between the amino acids.
