Initiator tRNA is in the P-site, Codon Recognition - rTNA anticodon matches to codon in A site, Peptide Bond formation - bond between AA and peptide chain in P-site b/c of rRNA acting as a ribozyme, Translocation - tRNA in P-site is released and ribosome moves down the strand, H2O is added instead of AA, freeing the polypeptide, another way to make multiple copies of a protein, all ribosomes are 'free' unless clued by the polypeptide to attach to the ER, missense - altered codons, still code for AA's, but not the right ones, Nonsense - changed codon becomes a stop codon (nonfunctional), results in longer polypeptides which may not be functional, causes frame shifts and extensive missense, nonsense, or sense mutations.
