What are the functions of the rRNAs, ribosomal proteins, small and the large subunits?
On which subunit are the mRNA binding, A, P, and E sites?
Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains.
–Small subunit: matches tRNAs to codons
- Large subunit; forms peptide
- bonds (contains peptidyl transferase,
- e.g. of ribozyme.
-mRNA binding sites are on the smaller subunit
