MECHANISM OF PROTEIN SYNTHESIS

• The actual mechanism of protein synthesis can be divided into three stages.
  • Initiation - assembly of a ribosome on an mRNA molecule.
  • Elongation - repeated cycles of aminoacid addition.
  • Termination - the release of the new protein chain.
• In prokaryotes, the factors are abbreviated as IF or EF for initiation and elongation factors respectively, whereas in eukaryotes they are called eIF and eEF.
