RNA CODON CHART HOW TO USE CODAN CHART

RNA CODON CHART HOW TO USE CODAN CHART TO DETERMINE AMINO ACID SEQUENCE

What is a codon? • Sequence of three bases on m. RNA that codes for an amino acid: • m. RNA 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.
