Protein Synthesis Involves Transcription & Translation
- The 2 steps of protein synthesis:
Process Where Major Components Notes Transcription In the nucleus DNA gene
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
Peptidyl transferase enzyme
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
