Initiation- consists of small rrna, methionine anticodon trna: ribosome recognizes codon for methionine and starts process of matching amino acids to codons, elongation- large rrna catalyzes reaction connecting amino acids using peptide bonds (dipeptide, polypeptide, etc. ), trna with anticodon for amino acid: termination- process hits a stop codon causing the whole process to quit thus making a protein.
