  1. Phases of translation:
    one: initiation; two: elongation; three: termination
  2. parts of initiation:
    Small subunit attaches to mRNA. tRNA attaches to start codon mRNA. Large subunit attaches on top.
  3. Parts of elongation:
    new tRNA molecule attaches to mRNA at the A site of the ribosome. An enzyme forms a peptide bond between the amino acids. The initial tRNA molecule leaves the P site, and the ribosome shifts, restarting the process.
  4. Parts of termination:
    a stop codon reaches the A site, a releasing factor enters the A site, and a hydrolysis reaction breaks the bond. The polypeptide chain folds into a shape and becomes a protein.
