									   RNA CODON CHART

  HOW TO USE CODAN CHART TO
DETERMINE AMINO ACID SEQUENCE
             What is a codon?
• Sequence of three bases on mRNA that codes
  for an amino acid:

• mRNA CODONS WITH AMINO ACIDS
  AUG – CCU – AAC      – GUA – UGA

 start – proline – asparagine – valine – stop

              PROTEIN
        (Chain of amino acids)
  Codon/amino acids chart
• The chart in the next slide is
  used to identify the codons
  that represent the 20 amino
  acids.
• It is universal, meaning that it
  is used by all scientists.
