Form 4 - Protein Synthesis



 

 
Protein Synthesis, Translation

 

 
Translation - the process of converting the mRNA codon sequences into an amino acid polypeptide chain.

  1. Initiation - A ribosome attatches to the mRNA and starts to code at the FMet codon (usualy AUG, sometimes GUG or UUG). 
  2. Elongation - tRNA brings the corresponding amino acid to each codon as the ribosome moves down the mRNA strand. 
  3. Termination - Reading of the final mRNA codon (aka the STOP codon), which ends the sythesis of the peptide chain and releases it.
