Protein Synthesis Involves Transcription & Translation

• The 2 steps of protein synthesis:
  

  Process	Where	Major Components	Notes
  Transcription	In the nucleus	DNA gene RNA polymerase	Gene is activated. A copy of the code is made from RNA (m-RNA) m-RNA leaves the nucleus, goes to cytoplasm.
  Translation	In the cytoplasm, on the ribosomes	m-RNA Ribosomes Peptidyl transferase enzyme Transfer RNAs	Ribosome decodes the m-RNA and makes the correct protein.

• Keeping the main copy of the genes in the nucleus protects it from damage
• There are many DNA repair mechanisms in the nucleus
